When do gmail invitations expire

Any approx. average?

If I didn't have use for one right now but wanted to wait, how long before it becomes inactive?

Do you mean you have invites and don;t want to give them away right now, or you received an invite and are wondering how long it will take to expire?

the first, the one i want to give it to is unavailable

I've had five invites sitting available for weeks now, and they've never disappeared. The number didn't go back up though when I used the sixth one a week or more ago.

I think that they have become a more or less permanent feature. Trouble is, most people who want a Gmail address have already got one (or several), so they're impossible to give away these days.

Heh- I emailed all six of the latest batch to someone using OS9. I was sick of looking at them.

Once the registration url is generated it lasts three weeks before it expires.

I kept giving them out and the next day I'd have six more to give - they've never "expired" so far...

Thanks guys, I'll just hang on and see...

Exactly how long does Google plan on keeping the closed door policy in place? Any ideas?
