Got the points in my account, even for my 2 family members who also signed up with their own email address.

I remember seeing a thread with some guy panicking that his points had not posted and getting really bothered by it---another flyertalker told him to wait for the end of the posting period. Although that exchange got (unnaturally) testy, I learned that , from now on, I will always wait for the end of the posting period. No reason to work yourself up over a few points when, chances are pretty good that they'll do you right.
