Wiki is for a for a feature we have and don't use much.

Comment does nothing interesting, table is a complicated collection of tags that you can use to make a display table in your post, and php lets you write out php code to let it look like code. Usually uninteresting.

H is to make headings, and Is something that I didn't realize was there, because it's pretty much duplicating functionality with size, just only doing bigger.
