lol,, and your first mistake was admiting you *know* about this stuff
Im sure the phpBB community would be very happy to hear of anyway you could reduce the overhead in recording something like that... I guess you would only have to record the unread posts and that the regular visitors records would be small,, but the occassional visitors records would be full... either way,, its still a large overhead,, and another set of calculations that need to be done every time someone requests a page!
Anyway, not something Im going to tackle, will leave it to the phpBB community to sort out... I have enough on my plate,, does my memory serve me correctly in that someone mentioned that a different colour scheme might be nice?
Glad thigs seem to be better after the domain change,,
