Ok, want to hear a real head scratcher?
Today, for the first time since last June, I was not prompted to login. When I can here to check this thread I was still logged in...
Coincidence?
Oh and the answer to every single question here is:
All of them are irrelevant.
Maybe I need to put this in bold:
Every forum I visit (except this one and except today) remembers my login information
There are no settings unique to this site, at least from my end
