Why the ID request?

[Dixie Belle]

Quick question to the forum administrators.
Why was I asked for my user name and password when I went to check out something in the Florida section but nowhere else in the forum after I had already logged in?
Is that Kosher or is their some sort of odd something going on there? I didn't give them, I just clicked out of that section. It was in the Florida 2011 season thread.
