OK, so it was a virtual move rather than a physical one. Our original idea to put the main landing page of Jivespace at dev.jivesoftware.com with the Clearspace community portion at www.jivesoftware.com/community turned out to be less than optimal. The original architecture made testing a nightmare and made many things more difficult than they should have been.
Last night, we deployed the re-architected site and completed the move to http://www.jivesoftware.com/dev and http://www.jivesoftware.com/community. We have redirects in place, so you shouldn't have any issues finding what you need, but you might want to update your bookmarks.
As with any upgrade, if you notice anything strange, please post it in the Jivespace Lounge, and I'll take care of any issues.
