is there a setting for it is is it automatic, I read a long thread then by the time I have wrote my reply it has logged me out.
When logging in, there is a box near where you enter your user name. It asks :remember me: check that and it will keep you logged in for as long as you want.
I had ticked the box but was still doing it, must be a privacy setting on my pc if no one else has the same problem.I usually have about three forums at once so that could be a cause too.
