Your criticism is appreciated and noted... it's always good to hear feedback, one way or the other.
One of the reasons why you may have seen "that guy" playing with vB options on his screen in your class is that RUL just upgraded to version 5.0, as mentioned in
this thread.
Rest assured that the parent thread/sub-forum links issue that you mentioned has been noticed and is on the list of things to correct down the road. In the meantime, those links ARE functional while browsing RUL in Internet Explorer. If you would prefer dealing with IE over having to stretch for the back button, switch browsers until it gets fixed
As for the rest of the suggestions, I completely agree with you. Unfortunately I don't know enough about the hard code to say how difficult it would be to integrate them into the new layout. I'll leave that for your classmate/site owner
Thanks for the suggestions!
