While moderating & administering the Projanmo Forum, I have seen many times that users opening thread in wrong forum/section. For example, they are opening a software troubleshooting thread in forum’s suggestion section.
I have seen in some vBulletin based forum that when opening a new thread, user has to confirm that he is posting in the right section. So, today I have made a very small extension for PunBB 1.3x bulletin board engine which will work it out.
When user is going to open a new thread, he will see an alert like the picture.
User can continue thread open only after confirming that he is writing in the correct section.
Hope this will save your moderation hour.
