The only way is go to the help pages:

http://community.wikia.com/wiki/Help:Changing_your_username (Sorry won't result in a link, just copy this in address bar)

It took them about 5 hrs to change the name. In the meantime you can't post using the account though.

Or create a new page and somehow inform your friends about the new name? My guess is that if they found this they'll easily find the name change if all posts stay in place...
