it wood be cool if there was a 'reply' button next to 'quote' and 'unquote'.
and when you press that button, a pm is sent to that poster, notifying him/her that you have replied to their post, quoting what they posted. rather than you pm'ing them bout something they may of forgotten bout in a thread.
that way, when you wanna reply to a certain post in a thread, the poster would know you replied to THEM
anyway, just an idea..
