Richard, and everyone else, prefers that you don't use marquees because it ruins the board for the users who don't like it. It also slows it right down for a lot of us.
He got rid of the html a few months ago for just that reason but that upset the people who like to use colours in their names so it was put back on the proviso that people didn't inundate the board with marquees.
We've seen how clever you are with html, now please, please get rid of it.
