When browsing the Wikimania main page:
the Boston and Toronto links from that page link to:
respectively. These links do not work (for me, at least), although
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.
