On every forum I've ever used I avoid the quote function anyway. Because when someone later tries to read through your thread at a future time because it sounds relevant to their future problem, then they find the whole thing broken up by blocks of repeated quotes, and the whole page far longer to scroll through than needed. Especially bad are cases where someone quotes someone who is already quoting another post...
I tend to prefer noting in my reply post the username or post number of a post I'm replying to, or if I need to quote something just copying and pasting the single phrase or sentence of the original text and showing it "just in normal quote marks".
