This forum software definitely leaves much to be desired. Quoting in replies doesn't work well, there are great differences in behavior depending on which browser you use, if someone edits a message in a thread, then the "jump to first new post" feature stops working, etc.
I have occasionally pointed out some of these deficiencies here. Then one day I thought, "Do I want the AP team spending their time fixing the forums, or improving the iFly product?"
Since then, I've decided to quietly live with the gimpy forums. :-)
