Why does it automatically mark all forums read even

[TeddyKGB]

when I don't hit that button. I haven't been on since this morning and I get on and my forums have been marked read even though there are plenty of posts that have been made. It has actually been going on for a few weeks now at random times.

I know it sounds petty but keeping forums marked unread is how I keep track of what is new and what isn't.

Thanks
