That seems like a lot of unnecessary clutter to me. If you are looking for a ride from a certain area on a certain date, type in the search query:
"carpool [location] [date]"
or just scroll through recent posts in the Room and Ride Share child board. Having 15 empty boards seems kind of pointless, and it's not like there's that much Ride Sharing being coordinated through the forums anyway. If you can't find something, post something stating what you're looking for a ride to, when, and where from.
