hi,
Wikipedia now has a brand new page for its 10th anniversary celebrations: http://ten.wikipedia.org/wiki/Main_Page and also has a new mailing list for the same - https://lists.wikimedia.org/mailman/listinfo/wikix-l
You'll have to create a login to access the wiki.
I have posted a note on the Wikiproject Mumbai today pointing to both Wikimedia X anniversary celebration as well as the Wikimedia Mumbai mailing list.
warm regards, Pradeep User:Prad2609
