Needs work for 1st Use
I read the reviews saying login problems etc, but downloaded anyway. I too could not register when I clicked registered user on the first screen. I tried using my Facebook account, google +, and join by email....nothing. I deleted the app and redownloaded. This time I clicked guest on first screen and checked out the features of the app then clicked register. This time I was able to register by clicking join by email. I joined, received my validation email, and was able to post a pin. Hope this helps others with registration problems.
