Quick Reply Reposition Mod is an SMF mod for version 1.1.x and 2.0.x mod. It re-positions quick reply from the bottom of the page to below the last post in a page. In order to use this mod effectively, the forum administrator will have to enable quick reply and turn it on or make it shown by default. This can be down via Admin CP > Themes & Layout > Member Options. By steps, I think you do it by changing current options for all members followed by configuring the same for guest and new user options of your particular theme. This mod is meant for default theme Display.template.php file but can be used to other theme with or without further modifications, depending on that other theme itself.
