avatar_58: Maybe I'm the only one here who regularly clears his cookies/cache, but I've had to use my key to get back into the site multiple times. My key has apparently been 'disabled' due to over-use.
I already emailed support about it, but I just wanted to warn other users. Don't clear your cookies.

ethanpd: Double-post... but it was giving me a 404 error every time I tried to post...
