Is there a MP like (read not RC like) site for mountain biking? Things like trail database, gear forums etc?

The closest site for mtn biking is:

www.mtbr.com/

Trails, gear, etc

Did the entire 'Your___xxxx___' link of sites all go offline and dead when Yourclimbing.com did a couple years ago? They had a whole bunch of 'your'sites, including ones on biking, running, etc. back in '08. Not sure if any survived.
