Monk...I just had a rather similar experience with a forum which I had joined a couple of weeks ago. My posts were completely ignored, and that leaves one feeling inadequate somehow, doesn't it! I did respond, and maybe i shouldn't, by calling their attention to this and calling them a "clique, which is repugnant to me!"
You won't find that here on PC, as I have been here for several years and received much helpful feedback, as well as responding to many posters myself, which was appreciated.
Love
Patty
