FORUM ISSUES: Report Upgraded Issues in this thread

Not sure this is really a technical issue but something I found confusing at first (and think I've figured out now). The Reply buttons are quite couter intuitive in their appearance. I'd have expected the big blue button on the left with Reply to Thread on it to call up the Reply dialogue where I could enter my reply but I think this is actually functioning as a submit button for the quick reply function. The button I was looking for was the linky type button on the right that just reads Reply.

Given that the quick reply area has it's own Post Quick Reply button, it's hard to see what that Reply To Thread button is really for.
