Presently, there are two main choices for general community discussions:
WaterWarfare.com Forums
Super Soaker Central Forums
Initially, it was hoped that WaterWarfare.com (WWc) would become the new community forum with members migrating from here and Super Soaker Central (SSC) to WWc. However, due to lack of time/access from the creators of WWc, that board has a spam-bot problem currently. Granted, the relaunch date for WWc is set for Sept 21, 2009, so there's still over a month between now and then for things to be fixed.
Of course, Super Soaker Central could be used as the main hub either until WWc gets up and running or indefinitely if WWc doesn't work out as planned. Using SSC is an option I'd definitely support, though, admittedly, I still would prefer to see WWc grow if its creators are willing.
Then again, when it boils down to it, it all depends on what the existing membership ends up preferring. Perhaps some will be content with the more limited nature of the converted iSoaker.net forums while others will end up preferring posting new threads and interacting at WWc and/or SSC.
In the end, time will decide where people end up going and spending their time.
As for me, I'll be around, just differently.
