Sourdough,
I'm basically a newbie. When I first started dropping in at Mudcat about a year ago I only read all of the threads, now with getting to know some of the people and making friends, and I am certain a few not so friendly, I feel completely free to post on any thread I wish to.
I do pm several members and E~mail others, but most I come into contact with through the Pal Talk / Mudcat Song Circle. That is where I really seem to get a better feel for the person I am trying to communicate with.
