Here's another interesting feature (?) of the site. I created two accounts yesterday, one for myself and one for my son. I did mine first and had no problem. When I attempted to create my son's I got the "Email address already in DB" message. I also had to enter his DOB more than once (initial entry screen and again later during registration). I know that I entered his birthdate because I had to think about the year. When I logged in today to change his password, I noticed that my birthdate was displayed on the Edit Profile screen. The option to change it is grayed out so I can't fix it. I've sent a message to POP so hopefully they can straighten it out.
Also, I don't remember if the registration forms asked but when I went to the Edit Profile screen the Gender selection was blank for both accounts.
