How to delete one's own post?

Now and then, I make an error in a post or for some reason it is no longer pertinent, and I want to delete it.  Can someone tell me how to delete my own post?

For lack of a better method, I have been using the edit function and deleting the text, and then reposting it as a blank post.  But there must be a better way to get rid of it entirely.

Thanks, Chuck
