Can anybody tell me how you qualify for Invites?? I've NEVER had any invites show up in my account!? Do you have to be with GV for a long period of time or something? (I've had it since last December)I've had my Google email account for some good amount of years...the request I sent was for my friend b/c she was getting ready to work and not able to do it herself, and I didn't have any to give out. I really wish I had some Invites to pass out!
