How can I add a color box for posters on my forum so they have the choice of what color to write their signature in?
I don't think you can do that. but you can do this on your forum open a new topic write whatever you want in your signature and color the text with color you want and put in the signature box then you will have color in your signature.
You can't, but you can use the color BB code.
[color=red]Your text here.[/color]
