First, it's a wonderful site, you do a wonderful job, you're a wonderful guy, and all that usual stuff. [:D]
But:
One tiny little thing could be improved, I think. If the cookies for "last time visited" could be for each individual board, rather than one global one for everything?
Reasoning: I don't necessarily hit the BIY board every time that I read the GD board. In fact, I've been lazy lately and sometimes have skipped the BIY board for days at a time (to my detriment -- I could've called TapCo on Friday if I'd read the board Thursday night). So, if the cookie is global to all boards (the current situation), I lose track of what I haven't seen on the BIY board if I look at the GD board.
