I have my browsers on various devices set to retain login info so most sites just remember me. For several years I've been logged into SBNation without ever logging out and thus never having to log in each visit. The past several days, when I go to ATVS or any other SBNation site I'm showing as logged out, needing to log in. Not a HUGE deal--though annoying--but the bigger problem is that it's not accepting my login credentials half the time. Sometimes I get in, sometimes I don't. I wouldn't think this is a platform issue. It's happening on a Vista system, Win 7, and my Android device.

Anybody else experiencing this? Any ideas?
