Editing?

[Aquattro]

You need to edit the entire thread to change the title, and I believe you need to own the thread.
No, you can't bump a thread without posting.

To edit the thread, click the edit button, then at the first page that comes up, click "go advanced" below the text box. That will take you to the page where you can edit the title of your thread.

Thank You.

Pretty sure it has to be done from the first post on the thread though.
