Maybe I'm an idiot, but I have more than 10 post and I still don't see any way to access downloads.
I think it is 11 posts... and then you might have to wait a bit before it actually unlocks, some folks have had that issue before. Once it clears, likely just a few minutes, just click MYDOWNLOADS at the top of any page, and you should get in there.
i first search on the net and find the downloads like this i access the downloads.
