Once and Again — the on-again-off-again drama - was dealt a set back yesterday.

ABC shut down the show's official Web-based message board Monday night. The board was a clearing house where fans had been venting their frustration about the show's cancellation. 

The board was part of the official ABC-run "Once and Again" web site, and the only part of the site that's been shuttered so far. Late last week the show's star, Billy Campbell, confirmed rumors that the series may return in the fall for a fourth season — dspite the fact that last week's episode was advertised by the network as its finale. 

Yesterday, officials said the entire web site will be shut down soon.
