18963 CSS Radius Corners

Hey there... listen, I'm working on a project and I've got the system done... now the client wants corners rounded.... I started playing with the nifty corners css tutorial but it's just eating my time... Now is anyone good at radius corners for all browsers.... well I am really only concerned with ie and firefox.... Basically if you could setup the code for me I can apply to all of my template boxes..... Thanks!! PM me for Url to see current site
