Okay here is the bottom-line. If you use HTML as your email format, when you click enter, you will be making a line break. Click enter twice to leave a clear space on your email typing screen and you end up with too many line breaks in blogger. So it may be easier to work in text. However, if you want to add a hyperlink then text will not allow you to create the hyperlink and it will not be hot in your text when uploaded to Blogger.
Now I am trying removing the link field on my blog to see what happens to my title of my post. If I do not hyperlink my post title, it is too small for my liking and so I am now testing the change here as well.
