In the Signature creating/editing area there is an list of code that is permitted.
Recommend you include a little popup window in that area that shows us non-programmer types the syntax for using those codes. I tried one, then viewed my handy work. All I saw was the text of my attempt. The syntax did not create my desired affect.
PS - I was trying to set a color for one word so it would stand out. No joy, this try. I managed to stumble through a few links where I finally found the info I was needing. So the information is available onsite. Perhaps a link from the Signature area to the information (http://www.linuxquestions.org/questi...o=bbcode#color
) might be helpful.
