You CAN edit your post:
You log in above, then the site returns you to the post. Do not try to click the "keep me logged in" box, it no longer works.. then IF your post is the very last one, you will see an 'edit my post' clickable on the bottom of your post. The moment a post is made after yours, you can no longer edit.
As long as no post is made after yours, you can re-edit over and over.
((And I just did it to add this message.))
