I really DISLIKE the feature of w3t saving my username, password, language, and some other variable in a cookie. I'm not really against cookies but there are some browsers that do throw fits when another part of the web site attempts to set a cookie with a different directory (w3t specifies it's own directory so I can't just set mine to path=/). All I have been able to tell these users is to upgrade to the latest browser version. Session support would fix this. Sessions are increbibly easy to support Scream, they're functionality is pretty much the same as your cookies all you would need is 1 function call at the top of your page and replacing your setcookie() call with session_register(). Also people with cookies disabled and people with old computers could access w3t because it would use append the session ID to the end of the URL instead of via a cookie.
For those who are interested, I'll release a hack for session support as soon as I see the PHP version of w3t.
Finally I'll be making hacks by the hundreds for w3t because it's finally in PHP a language I like unlike Perl (which should be banned by the U.N. from being used or something like that) <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" />
