I couldn't even sign up!  I kept getting told that I had to use at least one letter and one digit in my password.  In fact, I had more than one of each.  I tried using a different pasword, but the message was the same.  I tried to find an address to get help, but I didn't see an e-mail address.  Only in Gil Sideman's response above did I find a place to write to. (In a place to ask questions, I had to enter my (nonexistent) password.)
