Hot to rename a thread

[dflat]

@dflat: I saw the button but not a "change thread title" option. The title field is for the post, not the thread (from what I see...).

If you own the first post of a thread, I think you just re-title the post and the thread title should change. You cannot change the thread title if you are just posting a reply to the existing thread. If you want to test, make a new thread in the Sandbox and have a play with it.
