How do I change the master title of a thread?

[rweis]

I started a thread named:



Series 32 dc 12 volt electric motors - does anyone have any experience with them?



But it is not really a good descriptive title and the intent of the thread.



I would like to change the thread title to:



12 volt industrial electric motor as a lift pump motor



I changed the internal thread title, but the master thread title did not change. How do I change the master thread title?
