I normally define all css aspect (using some code like
http://www.votreespace.net/wbdemo/ )
so all is pre-defined, but they keep putting Comic Sans when you are not looking.
We Garantie great designs, passover the admin to the clients. Put this design in our "portfolio", but when somebody go see the site, they see bad design with big bag BOLD Comic Sans with red background!
I change that to be shure that my clients do not destroy my reputation!
