Going back to the original posters thoughts, I don't see where there are well-defined "cliques" on PC. Sure, there are posters who write more often than others, but I certainly don't notice cliques (except in chat - IMO). I think her perceptions were her problem, not anything having to do with PC. I've posted threads which have received little response, but just figure my posts don't click with others...they have nothing to do with "cliques."
