[boost] ! Wiki Spam

I just found the start page of the Wiki completely replaced with xanax drug spam. I removed the offending content and left a note in its place. Sorry - I'm not sure where the original content is archived or I would go fix it myself right now. Perhaps we need a password mechanism on the Wiki? This seems to work well over at http://www.program-transformation.org/ where you need to register and login to edit. - Chris
