They have mostly different users, but some of us use both forums, at least me as an admin. I have a unsolved configuration problem, which I suppose might be cookie-related. I'd like to get an easily understandable guide how to configure the forums to avoid the occurred problem.
If I login the old forum and then login also to the new one, the old forum kicks me out instantly. Vice versa, the same behavior if I try to login old forum when I am already logged to the new one.
