Did I put something in wrong?

Just got an invite today, which means that yeah, not getting any confirmation email beforehand was completely normal.

Same boat. I never got any kind of confirmation email, and neither have any of my friends who signed up, so I think that's normal... Either they'll send us an invite or they won't, I guess!

Don't know if it helps but I signed up and didn't see any email but the game one day showed up in my EA app library on PC and I am able to play.

Get in line, myself and others have signed up over a year ago and a mixture of EA's terrible RSVP system and actual sign up loops, made people think they were signed up when they actually weren't. 

Been in contact with them 3 times for me them to tell me there is nothing they can do. Can't even give me an answer if my account was ever signed up. The people working on here/you will be able to talk to are moderators and nothing more.
