How do I edit a post that is already submitted

[Mouse]

If you go to the post that you wrote and scroll to the bottom of that post, you will see an edit.

Click on the edit and do what you need to do. You can add images, change things around, or fix a punctuation.

When you finish, you have the option to say why you edited that post or you just hit the submit button.

The edited post will then be in there.
