I don't know what the problem is here as I have never experienced it.

On a controls forum I swing by pretty much every day, if you are inactive for about 5 minutes or so, it logs you out. Never timed it yet, but it appears to be about that.

Almost every time I post something I have to log in again, unless it's really quick. The timing considers typing a post or reply as being inactive. They don't get any spam either.

Only way to avoid the timer here is to become a lifetime supporting member, which isn't that much.

You can pretty much post any type of file on this forum directly from your computer or cell. You need to be logged in to view/download anything that is on their system. If a post has a general public item like a pic from photobucket or link to a web site, if the poster properly did this, then you do not need to be logged in to view/download.

It's just way too easy to directly pop in a file from your puter, rather than going the 3rd party rout.
