Some of you MAY find yourself unable to log in today, but you can read this forum so I am going to post this here.
I found myself unable to sign into B77 this morning, no matter how many times I typed in my login and password it refused to allow me entry. To get around this I deleted all my cookies (Tools -> Internet Options -> Delete Cookies button), praying I remembered all my passwords to get back into other places, cleared my cache (Tools -> Internet Options -> Delete Files button), and made sure that phpbber.com had the right to add third party cookies (Tools -> Internet Options -> Privacy tab (at the top of the miniwindow) -> Sites button -> then read everything and add www.phpbber.com to "allow all").
After a cold reboot of my machine, I was able to access B77 again. Hopefully this will help anyone else who finds themselves locked out this morning.
