I turn off the thread delete permission in my board ,so nobody can delete any thread&post except admin&mod.
In this situation, how to give permission to the first poster to edit his own thread title?

Thanks in advance!

I don't think there is any option as such, but I would personally love it if users could also edit their thread title.

I don't know if it helps you, but I answered this question here: http://vbulletin.com/forum/showthread.php?threadid=2574

I think you misunderstand me.
I mean the first poster has the permission to edit his own thread title ,but he has not the permission to delete/move any thread or post!

I understood perfectly.

I tried to answer your question, but I suppose you mis-understood the answer.

Yeah, it's my false, thank you very much!:)
