i've looked a looked but i cant seem to find any links or pointer to the windows7 connect site

sending feedback through the links all over win7 doesnt work either, giving an error saying im not alloed to post on the connect forum (this is true both for my regular liveID and the msdn subscription one with witch i got the beta) i suspect i need an invitation code but i cant find it anywhere on msdn and i havent got any email or anything :/
if any oneone knows anything about posting win7 bugs, please help me out.. im sorta bummed that its so hard to post bugs, isnt that the whole reason for having the beta? most people are far less inclined to help microsoft out (for free too) that i am and wont go through a tenth of the trouble ive gone though to get to post bugs.. microsoft is missing a lot of win7 feedback this way :/
