At this point, I actually am going to say no. TAC has been extremely nice to let us use theirs, and I think until we get more members, we should stick here. It's just one more thing to check. (Email, RSS feeds, news, 97 thousand forums...etc) As far as keeping topics low key, that's what email is for, and I will be sending out a spreadsheet with everyone's email in it along with the meeting agenda.
Don't get me wrong, I would support a forum if we did decide to make one. I think this would be a good topic for the upcoming meeting, so would you like me to add it to the agenda?
