Where it has the L | M | H, I want those seperate letters to link to the other sections when you click them, so it'll just move down the page to that letter or certain word. I don't know how to do that though.
That's not possible with BBCode. With Javascript, yes, but not for forums UNLESS you are using one post for one section, then you can just use the URL tags to link each section to whatever post.
So the only solution now would be to have a note saying to refer to whichever section. Unfortunately, FSD doesn't have spoiler tags, which would make organisation a lot easier.
HTML is basic-level, though.
