Downloading .pdf plans.?
I just registered with instructables and set up an account, and I have received my e-mail conformation. But when I click on a .pdf plan or drawing that I want to look at closer; I get a pop-up window that wants my username and password. When I login the window goes away, but no .pdf. This window also seems to want to sell me an upgrade to Pro. Does this mean that I am only allowed to look; but I can't download unless I upgrade to Pro?
