We seem to be having a glitch again where you click on the Log In button, but nothing happens. If you are having this problem, try clicking the "Stay logged in" box before hitting the "Log in" button.
I noticed page loads hanging earlier today. I always have "Stay logged in" checked, though, and so I can't remember the last time I actually tried to log in. (Probably after my last Supporter renewal, as I think you have to log out and log back in for the ads to go away...)
