After noticing that my invitation wasn't being sent to my beta testers, I decided to send a few invitations to myself to figure out whether I may be using some invalid character that was preventing it from sending or something. It turns out that the invitation has to be written on a single line, otherwise it won't send, and frustratingly there is no error message to tell you that it hasn't sent. Thanks Rob EDIT: Actually, don't worry about it; it's not much of a problem. It would be useful though to mention this on the beta invitation submission page.. Cheers
