I find it very hard to see what messages are unread. The sub forums show a counter, but when I click on the sub forum it doesn't show my what conversations are actually new.
Also after looking at a message from the all up view or from the view in the sub group it doesn't markt them read. I actually have to click on each message and see each response before it marks them read.
Makes my it super hard to have a 0 count and stay on top of things.
