I tried doing that with a symbols, but it didn't work. Is there another way to do this, or is it just not enabled? If not, it would be a great idea to have this enabled in beside the bold, italic, link, image, and quote codes. It is a much better way to point stuff out than Bold, and much easier to see than Italic.
Why wanting to have so many options? If we keep it simple, everything is better? Why would we need to have underlined and strike-through and colours? The colours are for mods (bad Zophia), the strike-through does not make sense (oh, I did not mean that I just wrote, strikestrike), and the underlined is a little annoying to read.
