Ummm... you can get colors, font size, font change, ordered lists... most anything, through VB codes.
If your forum doesn't already have them, do some looking and add them yourself. The "Add VB Code" function exists for just that reason.
We have several different ones availiable on our site:

See an example of several of them in action.
We have glow text, marquee text, Flash support... you name it.
