The Sanctuary Condo Association raised the value of its properties by 300% in a down market by launching this full-featured Web site. You say "Really?" No. Not really. But this Web site will make it easier for a time-starved condo association board to communicate with its members, real estate agents, title companies and collection agents. Ok, not collection agents. The site uses forums, content subscription, mass email and a bevy of other end-user-administered tools.
