Legal Update Text colours
Is your site legal? In August 2000, legal history was made in Australia, when the official olympics website was successfully sued by a blind user who found the site inaccessible (see Maguire v SOCOG). That should never have happened if the developer had shown due care and professional competence. More cases are in the pipeline around the world, and the numbers seem likely to grow rapidly as precedents are set.

Also, do you want users to be able to Print content, this gets it seen and free advertising.
Well who's paying for all that black ink!!!
OK! print out colours could be changed but will users bother doing this.
If you don't want users to Print use soon Java Script to stop them.
