I like wasdialup. It's like wassup, but with dial in between. fkadiu (an acronym to keep it old school). But you probably want to keep it pronounceable. My vote goes for wasdialup. Oooor wassupdialup. no that's just lame. Obviously I'm not very good at this. I name all the characters in the books I write Omar, and derivatives off that (Omar1, Omar2).
