a couple of interesting things on the forums at hardwaregeeks.com

The forum itself is kind of interesting.

The have an entire thread about gmail invites.

In particular, a way for people with spare gmail invites (like me) to hook up with people that want gmail invites (whoever they might be) at isnoop.net

By the way, this is also one place to read stories (success and otherwise) of free ipod offers and such.
