Note: you must use double quotes around your URL's. This creates nice xhtml. You could 'single' quotes if you really wanted to, cbparser doesn't mind, though if you do, the automatic tag case correction will turn your URLs to lower case, which may or may not screw them up. Use nice "double" quotes and all is well. There are other flavours of URL, too..
