On my board I have [mrt] says, which turns into a box with a picture of Mr. T that says "Mr. T Says" and then {param}. I also am making one for Yoda and other stuff.
What would be extremely cool and what one of my members brought up is a dynamic tag. For example, [filburt1]stuff[/filburt1] would be a box with my avatar and "filburt1 says:" in it.
But it's just too hard for Chen.
