Even if I'm logged in, my name doesn't show (which is okay by me ). But in case the same thing happens to someone else who does want their name shown, it might be because you're behind a proxy/anonymizer for http.
I guess you have to be logged in with the same address as the bittorrent client.

Why the extra stats? I guess honor amongst thieves doesn't really work, eh
I'll bet shame and scorn doesn't either.
