My wife and I have separate email accounts and we registered individually. I received my email about 7:40 this morning and she got hers about thirty minutes later. There is not a drop-down on the email you received that might contain your spouses' name(s) is there? It seems like I read somewhere that if more than one person was registered from the same account, you might get one email to cover both of them. I'm mostly guessing because this whole system has been so screwed up from the outset and they keep changing the way they do things, and do not give good, comprehensive instructions about anything. You might trying calling 2-1-1. I tried it the other day but got tired of sitting on hold and hung up. GOOD LUCK!

Just checked and my email confirming my registration was sent this afternoon at 2:13 p.m......now we're both good to go and just waiting for the next email.
