In case you're wondering why we haven't fixed the ratings bugs yet, we're in the process of going through the ratings system and seeing what works and what doesn't right now. Since we'll be changing a lot of the code, we'll be fixing the bugs (or working around them) when we implement the ratings updates.
On the topic of invitation counts - before we recorded invitations on if the user registered from the URL sent in the e-mail. We're now associating the user during the entire session (as long as they came to fanpop through your invitation e-mail). Now, if you receive a message telling you your friend has joined, then you should get credit for it!
