Y'know, if I were Mr. Diesel and on these boards, I probably wouldn't reveal myself. Why? Because all these "Hey, Vin Diesel talked about D&D again" threads make it sound like there are about 500 potential stalkers on these boards.
That said, there's a pretty good chance that at least one of the many celebrities known/rumored to play D&D frequent these boards. They may be posters or they may be lurkers. Hey, for all we know the next 'new poster' to get slammed big time for asking a question that we've all seen 1000 times before good be one of these celebs.
For that matter, that could have been the case last time someone got slammed. Who wants to step forward as the sweaty, overweight, pimple-faced geek who told Lexa Doig she was an idiot?
