When browsing the Wikimania main page:

http://wikimania.wikimedia.org/wiki/Main_Page

the Boston and Toronto links from that page link to:

http://meta.wikimedia.org/wiki/Wikimania2006/Boston http://meta.wikimedia.org/wiki/Wikimania2006/Toronto

respectively. These links do not work (for me, at least), although

http://meta.wikimedia.org/wiki/Wikimania_2006/Boston

does.

I've added a redirect for Boston, but I'm not sure if this was done deliberately or by some mistake. If this is done deliberately, I apologize for the redirect, and it can be removed, but it seemed counterintuitive to link from the main Wikimania page to... something that didn't exist.
