I feel ya for the wierd names and lots of red lines haha. When you first go to make a post, above where you put the text on the right there should be a thing that says markdown or editor. You can press that and type into the editor, and there will be options to make header text or itallics there ect. It helps add some diversity to the post and makes it look more pro too. Also, grammerly is great (though i find it works wierd on here). Hopefully in the future I will have more to give away :)
