I'm looking for a name of someone I know, but subeta search of course isn't working, so...how do I find them?

do you mean you already know their username, or you only know part of their username? if you know the whole username you can just type in subeta.net/users/NAME to go directly to their profile.

DUH! Oh, dear, how on earth didn't I think of that?! ROFL, thanks a lot <3
