Hi - I am running a reasonably large wikimedia site (a few thousand pages) and have thought for a while about a certain desired feature I have, which I suspect a number of other wikimedia sites might find quite helpful.
Background: Armeniapedia.org is for articles on anything and everything to do with Armenians. So, for example, it can have articles on anything from Yerevan to George Bush. Now the Yerevan article, in theory, should not need to be any different than the one on Wikipedia, while the George Bush article, should have only Armenia(n) specific information that would not be fitting on Wikipedia. Armeniapedia is also a good home for say online cookbooks, texts, etc, etc.
The idea: For articles like Yerevan, it would be nice to somehow synch my site with Wikipedia. If I could somehow specify that a certain article on my site is a sister article to Wikipedia, then allow the article on my site to automatically update itself on a timely basis (weekly or so), plus whenever someone wants to edit they get automatically taken to the wikipedia article's edit page, it would allow both sites to benefit.
I'm sure other ways of implementing this would be possible, but the basic idea I think (and hope you agree) is a good one.
Thanks for reading this...
