CZ Talk:Volunteer illustrators

Article/tutorial help needed
At least one of the volunteers (Howard) is proficient with PowerPoint graphics, as well as manual drawing and drafting. He could be much more effective, however, if there were some tutorial articles on freeware graphic software with which he has a slow start, including:
 * Gimp
 * Dia
 * Open Office Draw
 * Chemical structure package TBD -- I have to find the email in which David Volk told me what he uses.
