I love Tommy Rall! Also, message board crime-fighting.
All the accolades and discussion of Mr. Rall from imdb are sadly gone now, but hopefully people will chime in here! I thought the folks of moviechat.org had copied all the message board posts that were still left after an earlier culling imdb did, but I can imagine that would have been an incredibly huge task, so I'm not bitching.
Actually, the imdb message board on Tommy Rall provided the means to uncover an identity thief, who'd been impersonating Mr. Rall, using the dancer/movie star's fame for his own gain. Not only did he get stopped from doing that (Mr. Rall graciously declined to prosecute him, accepting the promise that the fraud would stop), but later the impersonator was convicted of further, darker wrongs, having to do with young students. Without the message boards, that guy would just have kept on claiming to be Tommy Rall.
