How to delete a thread or edit a post title?

[Flykoe]

Made an error on a post. Pressed a bunch of stuff trying to edit it and managed to add to the body but couldn’t change the title. Is it possible?? I’m embarrassed by the mistake and want to get it rectified. Please help! Thanking!

Instead of hitting the "edit" button hit the "go advanced" button
