How to edit a typo after posting in classifieds

How do I correct a typo in a posting in classifieds after it's been posted. I cannot seem to find away to correct or edit it.

 

Corncobcoupe,
I appreciate your help with the typo in my ad. Can you please explain to me how to “Bump“ an ad? I would like to refresh it without doing a whole new thread and cluttering up the page.
Any guidance would be deeply appreciated.

 

Thanks again!
