Also, as far as limitations go, the following are considerations; 1. You can't pass an array using the querystring 2. Multiline variables (ie. <textarea> contents) are bad 3. There is a limit of 255 or something characters to a URI (someone?) 4. Be careful with the $_GET[] array that Tony mentions, it is only available on more recent versions of PHP, before that it was $HTTP_GET_VARS and a lot of people had been using just plain $var1 or whatever, assuming that "register_globals" would always be ON in the php.ini file (which also changed in recent versions).
