I'll add that invites are getting increasingly easier to get. I signed up 3 days ago (thanks again) and was given 6 invites as of this morning.

There are rumors as to how invites are handed out. I've heard that it's based upon the use of your account. I've used the heck out of mine -- probably sent over 200 emails in the past few days. Another rumor is that if you start a blog site, you'll be rewarded with invites (I gues that only works if you list your gmail address as your email).

The second one may have something. I started a blog page last night and within a few hours had 6 invites waiting to be given out. Also, after you've given out invites, I'm told you're soon rewarded with more. Google seems to have taken a 'viral' dissemination strategy. I think it's pretty cool actually. Will make it much less likely that spammers will be using gmail accounts as they are somewhat limited in availability.
