Yeah it's always kinda annoyed me but it's one of those things you get used to over time I guess.
Might not be up to us to extend it though. If the forum is hosted on a shared server (which I think it is) then usually you cant decide these things. I'll bring it up to TBF and the other admins and see what we can do about it.
Another solution for now would be to tick the 'remember me' box before your next log-in so that you get automatically logged in every time you browse the forum.
I believe this'd solve your problem for now TDK but try to copy your message very often before posting too.
