Man.

So I said my auth method had changed. Then RSS was broken because somehow the Deny users="?" tag got in the web.config. That kills non-authenticated users, which made the RSS feed redirect to login, which broke it. Then once I figured that out, I couldn't log myself in. Then I remembered that, out of frustration, I changed my password to something....vulgar...and I had forgotten. So all is well now I hope.
