Hotmail and Yahoo are sending Gmail invitations to the trash. I'm wondering how many of my invites are actually making it to their destination because I have many unanswered invitations out there.

There is a way around it though. If an invitation you have sent is diverted by the Hotmail Spam Gods, then you can go into your Gmail Sent folder and forward the message back to the recipient. I just wish there was a way to view all of the "unanswered" invitations so I could either resend them, or send them to someone that is actually interested in having Gmail.
