There is a reason why GM's control the naming. If this option would be given to everyone, there would be naming kaos. GM's are just sitting around hands on their laps, waiting for those thread renames to fix. Get real.
Who is currently defining the thread's names? The GMs? NO - the users are doing that.The GMs may update an unarppopriate name, exactly like what they would do in case that this suggestion will be implemented.That is their role, and it would not be changed.
1. i just like to add, that we don't get paid and do it in the spare time. And there are lot of other arguments of it, which will affect the usability of the forum in future. And at least speaking for me, i don't like to work for such thing in my spare time.
2. or thinking first about an title before, such cases like you mention are more then rare without that it makes sense to open a new thread instead.
3. it will flood the new thread showed on the left, so it affects search.
As I said, you can just display the thread's name a user last saw, and not the other.
You don't really seem to understand the consequences of this suggestion. You seldom seem to even understand your own suggestions. So if we would allow the thread name change - the thread get's changed by user, get's changed by GM, user can then again change it. The loop continues. There is absolutely no need of this. For gods sake, this guy needs a cooloff from forums. Atleast a warning would be long overdue.
