A Mac group that I belong to has started their group on Groupbox. These guys are experts on the net and I really trust their knowledge and instincts. They checked out quite a few groups including the ones mentioned here in this group.
Sorry Mystic for missing your post!!!! I'm so stressed, I'm so sorry
It does look good! I have a couple of forums in progress right now if these don't work out we will definately check groupbox out, thanks for the link!!
