Bug 2 of 3.

Since I really wanted to post my inquiry on the forums, I decided to give it
another try. Now that I knew dashes are not welcome, I went straight for
re-creating "zlatkomichailov" again. To my surprise, it told me that that
account is already in use. Let me reiterate on this - you told me you would
delete this account, but you didn't. I take it as a violation of my privacy. I
am sure you think you have reasons to keep it. They are no good. Unless you
make users agree to your retention policy before they create an account,
delete.
