How does the rideshare thing work?

When I first built this site I had a dedicated rideshare section. No one was using it though, people seemed to prefer just to use the forum, so I deleted it. However I forgot to turn off the thing that let people post rideshares - I've done that now.

So now just go to http://www.climbnyc.com/forums/social/climbing-partners to look for or advertise a rideshare.
