It would be ded useful in loads of stuff.
For instance, the spider thread that was titled "Oh My F**king God" - that offended loads of people and the poster was very very apologetic. I'll bet she would have changed the title if she could and then it wouldn't have kept popping up in active convos, same with some of the ante-natal threads that had dodgy titles.
Also, sometimes I start a thread and wish I'd done a different title, but I'd have to do a new thread if I wanted to change it, wouldn't it just be better if I could edit the title and change it?
So is it possible then?
