Mark as read modification

[SloppyGoat]

I'd like a hack that either makes parent forums mark their subforums read, or subforums that also mark their parent forums read. It makes no sense to me to have to mark both parent and subs read each time, even if there are no new posts in the parent....if that makes sense.

If this has been done already, please direct me to the hack. If not, does anyone think this can be done? It would be very much appreciated. It's been urking me for awhile.
