I was introduced to Mudcat about a month ago by a friend who suggested I reply to a thread which concerned some folks I sing with. Since then, I 've read some extraordinary exchanges and been impressed, amused, and moved by the sense of community found here. So I've joined up, by golly, but I feel a little like I'm sitting at a new session for the first time, not ready to open the case or clear my throat for feel of making a honking noise, or violating a custom I haven't yet figured out. Any tips on custom or protocol? Thanks, D.
