Found Dreaming

On a different forum I frequent, we have a showcase section there you post your completed project start to finish, usually the original poster just edits his first post and adds content while if someone wants to comment they just comment at the bottom, it works quite well over there...

on a different note, a nice feature to incorporate into this forum (if possible) would be to add a notification system that would notify you before submitting a reply if someone else have already posted a reply in that thread...just a thought...

phpBB3 has this built in and should be with the settings here enabled in all forums

Enable post review:
If set to yes users are able to review their post if new posts were made to the topic while users wrote theirs. This should be disabled for chat forums.
