Nor would I. On guitar boards, I have run into a few pros. I don't mean guys who are studio musicians or who gig in and around a large population center, I mean guys who have been on world tours and have albums that charted.Actually, I wouldn't doubt it. I've been on other various boards, many motorcycle related, and we've ultimately found that well known journalists and racers were on them using pseudonyms. It's a very real possibility.
SOME of the use their real names, but they're the exception.
