We seem to be getting an influx of "new blood" lately (though the people aren't so new - all of the old VN crowd finally making their way over).Well, we had a bit of discussion a while back on one board versus many and it was basically decided that (after you get used to it) this way is easier.
There has been quite a bit of discussion on the best way(s) to keep up-to-date on the New messages. If you use the search feature of the board and look for "read new message" in all boards, that should give you the low down.
You could start by just reading the tips in the "About the board" forum ... that should be a good start.
