How to change the title of a thread?

[THE BLUE]

Okay, here's the thing; I recently created a thread in "Electronica Express" by "Britney quits pop music to become a forensic scientist". The source turned out to be old and I wanted to change the thread for I couldn't manage to delete it. I went advanced while editing and named it "Larry King pressures Jodie Foster to come out". The thread somehow goes under the Britney title and I can't seem to change it.

I've edited the title.

Yep, I see you have merged the two threads.

No, I just changed the title as you requested.
