Today we (Enthusiast Group) made our first site live. It’s not a launch per se, more of an early beta version. (Does that word even mean anything any more?) We have several features still in the pipeline and there are doubtless many bugs still to be ironed out. As a matter of fact, I just found and fixed a couple between the last sentence and this one. 
So go check it out and let us know what you think: Mountain Biking at YourMTB.com
