Just my 2 cents----I have to say I love this forum but I've gone from a long time lurker, to frequent poster (for a short while) now back to mostly a lurker.
But that's because I feel I don't really have much to offer, or I might go off on a tangent which probably annoys some as the post might seem off topic.
Nobody's made me feel unwelcome, I've put the brakes on myself.
This is a very friendly board.
It does seem alot of the posts are from the same people, but that's to be expected. There are always "leaders" and "followers", (I'm definitely a follower). It's not a bad thing here since the "leaders" are so helpful and patient.
I've lurked on other boards and found some attitutes that turned me away.
I've posted more here than anywhere else.
I guess what I'm trying to say is I don't think there's any one reason why others might leave, it's probably because their life got in the way. I don't go into Chat or PDA so if there were tensions there I have no knowledge of it.
