With the exception of very limited use as a way to highlight a section of a post (i.e. one or two words), I find the overuse of the color tags to be very annoying. I am generally very tempted to go in and edit posts like that.
Perhaps there is a way to automatically set a background color for their posts which is complementary to the color text one decides to use?
Or people could just learn how to use HTML span and style tags if coding the board to automatically change the text background would be too complicated.
