I had some contact with them recently, via groudspeak emailing, regarding my "blooming" embarassing DNF. I see they last logged in 27th January, but they were responding to email before that. They did send me a friend request which I accepted, would this help regarding contacting them? I have no idea what 'functionality' a Groundspeak friend adds, could you maybe shed some light on this?
