I noticed a couple of times that I am not able to log in.
I tried going into a thread and try it there, did not work at all.
Until I clicked on news tab at the top, then log in. Then I got the pop up box in the center of the screen to let me log in. It seems that is the only place it will work for me. You may not get any complaints because you have to log in to complain. :)
Thought you may want to know.
