As far as I know, in the past, when I need to change my thread title, for example if price changed, I PM a moderator to change it.
Instead you could add a feature which makes you change your thread title for points (1000-5000 points). Then moderators would have more time to deal with other important things such as scammers.
I can think of that people would need title change because:
- On a buyer/seller thread, the product price can change everyday, so seller/buyer can keep their price in the thread title "updated"
- Add new product to a title, for example when MOP Keys came out I PMd a moderator to edit it in
- Any update that needs to be noticed
(I also noticed in every forum you must PM a moderator to change title and I have no idea if its "dangerous" in someway to be able to do it yourself, the only bad thing I can think of is if a scammer made a topic to sell something, then he can just change it and say he didn't (but moderators could check the title change record history anyway?).
