In reply to Bertbee:
Being able to join a group or club would be a cool feature for this site, as an extension to the climbing partners feature I suppose. Users could add a club to their profile, and any user could view climbs by a certain club. Or some combination of privacy options (viewable by friends, viewable by club, viewable by public).
Could help encourage a few clubs if some people getting out is a bit more visible - was it Cameron who coined the phrase 'nudge theory'? I'd have thought it possible for UKC to design a little button or what not that you can put on your club website and flashes green if someone has done some routes that day or something to entice people to come and visit UKC.
Everyone's a winner
I guess it depends on how hard it is to code and UKC's spare time to implement it.
