Main Page

Welcome, new editor! We're very glad you've joined us. Here are pointers for a quick start. Also, when you get a chance, please read The Editor Role. You can look at Getting Started for other helpful introductory pages. It is essential for you as an editor to join the Citizendium-Editors (broadcast) mailing list in order to stay abreast of editor-related issues, as well as the mailing list(s) that concern your particular interests. It is also important, for project-wide matters, to join the Citizendium-L (broadcast) mailing list. You can test out editing in the sandbox if you'd like. If you need help to get going, the forums is one option. That's also where we discuss policy and proposals. You can ask any constable for help, too. Me, for instance! Just put a note on their "talk" page. Again, welcome and thank you! We appreciate your willingness to share your expertise, and we hope to see your edits on Recent changes soon.

Mar(r)iage card games

Hello, Hans! I saw your new article on "Mariage card games" and I wondered whether the first word was misspelled or not. Is the name the French word "mariage" (with one "r"), or is it supposed to be the English word "marriage" (with 2 "r"s)? Thanks. Bruce M. Tindall 21:04, 13 March 2009 (UTC)

Wow, it's nice to get feedback that shows even such an unfinished article is already being read. It's supposed to be French, as in David Parlett's OUP book, because apparently the "marriages" came from France and were added to the German 66 game, which was then known as "Mariagenspiel" (German for "game of mariage"). The Czechs and Slovaks are still using the French name in transcribed form. I believe the game never caught on on the other side of the Channel or Atlantic.
Thanks for asking. I have just gone through the process of renaming Jass–Belote card games, so I am well aware that some people might not correct a typo in the title because they are afraid of the process and don't want to bother anybody. And the decision whether to translate in this case is far from obvious.
PS: I just copied the Usertime-text template from your talk page. Very useful. --Hans Adler 13:56, 14 March 2009 (UTC)

Non-Borel set

Hans, could you please look at my new article Non-Borel set? It is a short article intended for a reader not acquainted with descriptive set theory and curious to know whether a specific example of a non-Borel set can be constructed.

Your comments are welcome, the more so that I am a newbie here. Do you think this article should be developed further? If so, --- in which direction? If not --- can it be approved? Boris Tsirelson 17:51, 20 June 2009 (UTC)

Boris, welcome to Citizendium! I haven't been here long and I am not as active here as I would like to be. Wikipedia is much more lively, and with its masses of unreasonable users it's quite an addictive game.
I had the impression that Citizendium favours larger articles and prefers not to have masses of little stubs like Wikipedia does; but I can't find this in the official information, so I may well be wrong. I am not really familiar with (non-)Borel sets, but I would have thought that the natural place for an example of such a set would be at Borel set. According to CZ:Approval_Process#Overview, an approved article should be "so well developed that it gives the Citizendium reader a good introduction and overview to its topic". I guess you have intentionally chosen a very narrow topic, but perhaps it was a bit too narrow. Looking at some of the articles in Category:Approved Articles, I get the impression that you are overusing the specific CZ features, and this makes the article even shorter.
Getting an article approved is theoretically as easy as getting another mathematics editor to sign it off. In practice the standards seem to be somewhere between Wikipedia's GA and FA (plus correctness), and Category:Mathematics Approved is woefully empty. But don't take what I am writing too seriously – I am very inexperienced here. Hans Adler 22:07, 20 June 2009 (UTC)
I see. Thank you. Boris Tsirelson 04:43, 21 June 2009 (UTC)


Hi Hans, how come you started out with the metadata? I've never seen this before. I agree that the documentation is not the best and that a drop-down menu or so would be better (similar to the Image upload dialogue). It is just that someone has to write those things, and we haven't had a lot of personnel her lately. Anyway, some restructuring of the metadata is already on the CZ:Wishlist, so feel free to add this point in. --Daniel Mietchen 22:32, 12 December 2009 (UTC)

Hi Daniel, are you referring to my shouting edit comment? When I get a page with a huge template I generally try to fill in everything I can. I made exactly the same mistake in February, when I created Jass–Belote card games‎. The problem is that the documentation told me to pick a workgroup and put it as the "cat1" parameter. The obvious workgroup is called "Games Workgroup", so I was led to use "cat1 = Games Workgroup" instead of "cat1 = Games". I am not sure what the normal behaviour would have been. Not looking for a workgroup in the first place?
If it doesn't affect a lot of other people it's fine. The shouting was mostly so that I can find it more easily when I create my next article. (Perhaps I should have taken into account that this is a more quiet place?) I didn't want to repeat that mistake because I thought it might have side-effects. I have no idea what these templates are doing in the background.
... Or did I fill in some metadata that I shouldn't? In any case I was prompted to create the metadata page at some stage when I followed "Start Article", option 2. Hans Adler 01:36, 13 December 2009 (UTC)
Ah, that was it, thanks — will look into the Start Article option and perhaps adapt the phrasing in the preloaded metadata. Such helpful SHOUTS are fine! Cheers, --Daniel Mietchen 01:45, 13 December 2009 (UTC)

Returning to Citizendium: an update on the project and how to get involved

Hello - some time ago you became part of the Citizendium project, but we haven't seen you around for a while. Perhaps you'd like to update your public biography or check on the progress of any pages you've edited so far.

Citizendium now has 16,915 articles, with 0 approved by specialist Editors such as yourself, but our contributor numbers require a boost. We have an initiative called 'Eduzendium' that brings in students enrolled on university courses to write articles for credit, but we still need more Editors across the community to write, discuss and approve material. There are some developed Mathematics articles that could be improved and approved, and some high-priority Natural Sciences articles that we don't have yet. You can also create new articles via this guide, and contribute to some Mathematics pages that have been recently edited - or to any others on Citizendium, since you're a general Author as well as a specialist Editor. You may like to contribute to discussions in the forums, and might consider running for an elected position on the Management and Editorial Councils that oversee the project.

If you have any questions, let me know via my Talk page or by leaving a message below this one. Thank you for signing up and reading this update; I hope that you will look in on our community soon. John Stephenson 16:15, 30 October 2011 (UTC)


You might like to have a look at what's said about mathematics here. There's been some discussion already. Peter Jackson 10:50, 10 November 2011 (UTC)
