Due, I believe, to the numbers of members we have posting here on PC, things move pretty quickly. And, depending on when a Thread gets posted, sometimes it can get missed. Also, I think, members tend to get to know other members & so routinely reply to their posts. It can take a while to develop a circle of "friends". But, hopefully, it does happen, over time, for most members. It is important, in this regard, to post often; both new Threads of one's own as well as replies to other members' posts.
