Blocking Instant Messanger Services

[Greasemonkey1]

Hello,

Does anyone have a list of ports for all the messanger propgrams out there. I like to try to block some of the most commonly used one here at work. Also if some have put together a list of website already that we shoudl block like Myspace and Youtube it would be really helpful. Thank you for reading this.
