Possible to change thread name?

Hi, as the title says, is it possible to change in any ways the title of a thread. Because I build up comments and reputation and suddenly I have to start new thread because the title gives wrong information. If it is possible, please also tell me how I can do it. Thanks.

You can request a thread name change via our [Only registered and activated users can see links. Click Here To Register...].

Just write the new name into the field. :)
