I signed up for a logon to Space.com message board weeks ago. They never sent the email about activating the account. I cannot logon. If I try to re-apply to that same logon name, it says already taken. It was NOT already taken when I signed up: I went through the whole procedure and the site accepted the account and logon name. The logon is already taken because *I* took it. They just won't let me use it.
