1) login vs register are confusing (I assumed it had two login windows, until I looked at the button difference) 2) clicking on any message causes new window, terrible. No way to click back, but to close a window. 3) opened messaged -> tried to reply -> no indication that it is waiting to post the reply (maybe disable the 'send' button and rename to 'sending, please wait')
