howdy go and welcome to the board. If you haven't had a chance yet (and while you're recovering) pop on over to the "getting to know you" thread and spend several hours giggling at us and then - if so inclined - tell us something about you!

as for the knee: you injured it in June and just went to the Dr 2 wks ago so you probably continued to aggravate the injury during that time. Give it some time and some rest - it'll get better and the bike will wait for you! You'll thank yourself in the long run my friend!
