Sarge, some thoughts to avoid having to leave forums in a fit of pique in the future.
1. Lurk for a while to get a feel for the group and it's history to see if you will fit in.
2. Make your first thread on the introductions forum to let the members know who you are.
3. Before you start posting threads, make some comments on other's threads.
4. Respond respectfully to comments and questions posted on your threads.
5. Don't, within the first few days, start a thread bitching about the provincial nature of the forum members.
6. Don't, when challenged on TOS, act all whiny and defensive.
