I guess I feel like I'm part of the forum most of the time. The thing is, I go between regretting that I'm not "in" with other forumers enough and lamenting that I'm too far in. I think 5 well written and well thought-out, constructive posts a day or so is a good ideal for me to try and stick by, though anyone could look through my posting history to see when the last time that happened was.
But anyway, I feel like if I make too many really long, thought out posts I'm being snobby and wasting too much time online, and if I just make a lot of little hit-and-run posts I'm being annoying.
