The SVG Wiki was once maintained at svg.org but had been overrun by spammers by March of this year. Rob and I had tried to clean it up a little but the open nature of a wiki made this a losing battle when the other side has automated spambots. Unfortunately this wiki was referenced all over the web, including by the W3C itself. Doug Schepers has made an effort to shuttle the wiki over to its new home at http://www.svg-whiz.com/wiki/ and secured it (accounts by request only). I'm glad to see this great resource has a new lease on life!
