First mistake I made was: I didn't know how to use the tags properly, at the end of the post, and I couldn't post. But I figured it out.
Then I couldn't figure out how to put an image into the post, made search, and figured it out.
Now I cannot figure out how to use the new WYSIWYG feature of the editor. Whenever I push a button, it applies the button to the full post. Not just a specific selection. I don't want ALL the post to be headline, obviously. :D
