Though most of us probably love the name Wikimania for our favorite world wide event, it is likely to be necessary to "change" it, as "securing" it (domain names, trademarks...) will cost us much.
This is really unfortunate, for continuity reasons if nothing else. How much are we talking about?
WikiCon? Wiki2006? (2007, 2008, etc)
I do like ManiaWiki, though.
