Question... Often I logon the board, check for PMs and look at a thread or two, then, uh, er... go back to work.

But the next time I check, probably hours later, it assumes
that I READ all the posts that were new before.
The 'new' marks are gone. Is there a way to tell it 'assume I didn't read any of these' or even anything less drastic?
I know I'm missing a lot of things, and when I have the time I'd like to read them.
I read a post a while back about changing the number in the URL search for new posts, and tried it, but it didn't work.
Thanks!
