Hey! When you update your profile, there are some options...under "Look and Layout Preferences," there's a list of boxes that can be checked and a couple are:
Return to topics after posting by default
and
Don't warn on new replies made while posting.
and near the bottom, a box with the option
Use quick reply on topic display with a dropdown box and the options:
"Don't show at all"
"Show, off by default"
"Show, on by default"
