I have a feeling a lot of posters are simply like me .... and just simply don't PM people. It's nothing personal or anything. I just don't do it. I am here to post, not send PM's back and forth to people. I don't receive many PM's but the ones I do receive are typically complaining about something I said, to which I simply tell people back in return where they can shove their attitude.
But I just don't initiate PM's with people. Nothing personal and nor do I take it personal that people don't PM me that often.
