My e-mails haven't gone out to my team!
Whilst I won't rule out there's an issue with the system, it's entirely likely you've already said you're playing (or not) for that game.
If you put your registration down before the invitations go out, we won't send an invitation. After all you've already said what you want to do. Asking you again would just be spamming you ... and we try to avoid that :)
Until next time,
