I be Agnostic, if you please.
Gonna have to disagree with Moose here. I tend to think that, at a push, most atheists would agree that they cannot totally deny the possibility of the existence of God/Gods without moving into almost a "faith" position. So technically, one could regard them as agnostics as well.
Maybe this is true of some theists as well (that God/Gods might possibly not exist), somewhere in the dark recesses of their minds...
this would of course swell the agnostic camp substantially
