I see what you mean in a way. I am pretty new and the first couple boards I posted on I was totally ignored! People seem to branch off into their own little chats/debates.
I felt ignored at first, too. The only thing that kept me from leaving was the fact that I felt that God wanted me here (plus I didn't really come to the site looking for acceptance). I am just now starting to feel accepted, which is nice, and I realize that it takes time to get to know new members, so I understand and everything, it would just be nice to be able to support the good posts that don't quite deserve a rep point
