I have a question for anyone with an answer ... !
How come I can be logged in in the evenings during the week and I'll have to re-log-in a few times even when I'm posting to threads.
Yet today, a Sunday, I logged in this morning posted a few posts then went out for the day. Hours later I come back and I'm still logged in .... whats the deal ? how does it work ? On what clock or cooky is it based ?

it's a session cookie with standard php sessions

edit:
and it's saved in a tmp folder.
Maybe if the command "session_destroy()" fails then this tmp file isn't deleted and you join the same session even after days.
But you're right, it's weired sometimes
