5 posts plus (I think) 4 hours of "total time logged in." I also think you must be actively searching the forum in order to accrue time.

It's really not so bad. But one thing to keep in mind is that the forum seems to only keep track based on your last click when you are logged in. So if you click a topic and then spend an hour reading it before clicking again it seems you get 0 (or perhaps 1) credit for minutes because the forum doesn't know that you spent an hour reading. OTOH if you read for five minutes and then clicked you would get credit for five minutes.
Anyway I'm able to post elsewhere but I think I will stick around here for a bit until the questions asked here are no longer interesting (indicating that it's time to move to the other forums).
