Is there any way to edit Thread Titles?

I'm running a thread for the Southern Hemisphere Growdown Throwdown, and voting is closing in a few days.
The current title is 
"Southern Hemisphere Growdown Throwdown - VOTE!"
 
But I was hoping to change it once the variety is determined.
 
Is there any way for that to be done?
 
Thanks, TBG

Click on your original post, click EDIT POST, click USE FULL EDITOR, that opens up a full screen where you can edit title, tags, etc.
