Welcome to the Citizendium! We hope you will contribute boldly and well. Here are pointers for a quick start. You'll probably want to know how to get started as an author. Just look at Getting Started for other helpful "startup" links, our help system and CZ:Home for the top menu of community pages. Be sure to stay abreast of events via Twitter. You can test out editing in the sandbox if you'd like. If you need help to get going, the forum is one option. That's also where we discuss policy and proposals. You can ask any administrator for help, too. Just put a note on their "talk" page. Again, welcome and have fun!

Welcome and thanks

I'm just spending some time this morning thanking the newer/returned people who have been doing work on the wiki lately. So, thanks, nice to have you here! --Larry Sanger 09:39, 17 November 2007 (CST)

Hi and welcome

Cryptographic key vs. cryptosystem article

Thanks for catching the errors in cryptographic key. I'm not sure, however, that the comment on stream ciphers belongs in an article specifically about keys, unless there were a discussion of stream keying (and perhaps autokey) in its own section.

We may need a survey article, however, about modern cryptosystems in general, and techniques like stream, block, etc., ciphers, as well as OTP, algorithmic approaches such as Feistel, etc., might be better there. What do you think (note copied on article talk page) Howard C. Berkowitz 11:56, 31 July 2008 (CDT)


Здравствуйте, Андрей!

Скажите, а что Вы думаете о перспективах открытия русской ветки Ситизендиум? Многие из ру-вики готовы участвовать в этом проекте - но отсутствие беглого владения английским языком - сильнейшее препятствие.

Привет вместе,
я думаю, что время иноязычных веток пока не пришла, ведь участников мало даже здесь. А стоит, наверное, немножко придумать о том, как или под какими условиями лучше начинать такое. Мне тоже кажется, что русский был бы хороший кандидат.

Я-то отношусь положительно. Но когда это еще будет... Andrey Khalyavin 07:23, 10 June 2010 (UTC)

Рецензирование Russian Revolution of 1917

Привет Андрей,

можете рассмотреть эту статью? Знаю, что она не по Вашей специальности, но думаю, что все-таки стоит иметь Ваше мнение об этом. Спасибо!
