In simple English, describe Edit HYML source, superscript and subscript and how to use them. I have never use them. Thank you.
Edit HTML? You almost NEVER have to touch it.
I use it to clean up stuff I cut/paste from other sources, and that only. (That "clean html" button sis really handy)
Superscript and subscript is for exponents, subscripts, and so on. Unless you write math and such you don't need them.

You obviously don't sew. When you sew and you have to make your own patterns, you need that stuff all the time! Figuring out how much fabric you need, or drawing patterns, requires a really good knowledge of and ability to apply mathematical formulae. Putting those formulae in laymen's terms is another topic in itself! (If you think you don't need it, try fitting a tight peplum jacket without a knowledge of conical sections or solid geometry. Calculus actually made my life much easier when I had to make my own clothing.)
In HTML, it's actually not that easy. Fortunately, there is an easier way, at least for superscripts 1-3. Simply click the character that looks like an omega from the text box, and look on the third row.
For a good explanation of HTML mathematical markup, see this page: http://www.w3.org/MarkUp/html3/mathscripts.html which gives quite a good explanation with examples.
The html button is handy if you want to add some html, from the likes of AmazonUK. (might have a million other uses, but that's the only time I use it ).
I only use subscript and superscript when I want to move a number - for example h2O, or 42.
Actually I have no idea how to use them in the forums, but subscript would make to 2 in H2O dip and the 2 in 42 rise, handy if you are using any mathematical formula.
