It happens for me no more than once a week for me and is down 1-2 hours usually from the time I first try to get on. It may happen more often when I'm not on...
I've seen the white screens a couple of times in the last week or so. This isn't the only forum that does it. There's another forum I'm a member of that does it every once in a while too. Does anyone know what causes it to happen?
