Well, I don't sing where anyone who is neither a close friend or VERY understanding can hear me, and the only instrument I sorta play is the bodhran (and it's status as an instrument is often a matter of discussion). I also share the varied talents of JotSC.

I read many more threads than I ever contribute to (and I'm sure that the issue of whether or not these are really contributions could also be a matter of discussion). As a student of history and an admitted pedant, I tend to barge in most often when people are misusing historical facts, deliberately or not.
