OT - Personalized Geek License Plate Ideas?

Hey everyone...
I'm thinking about getting a personalized license plate with some geek
theme to it. The max is 7 letters and you can check if your idea is
already taken here:

So any suggestions from the audience? SYSADMN and NETADMN are
available... SU is also available, although I doubt anyone, even most
geeks, would recognize what it meant. They'd probably think it was my
initials or something. USENIX is also available...

I look forward to your suggestions!
Thanks,
~M
