I have always used the URL www.sagenb.org. Today I used that, tried to log in using my google account, and accidentally typed a different username. It turns out I created that account (somehow linked to the same google account) a couple of years ago. Now when I try to log out of that and log in to my usual account, I am unable to - sagenb simply skips the part where I enter my username to access my worksheets.
I tried using sagenb.org (without the www), but when I do that, it says I can't use my username because it's already in use.
Ideas?
