by why me worry?

for every URL you block, there will be others that offer the same service. Stuff like AIM and Yahoo Messenger all use TCP ports for connecting to the messaging server. By blocking the TCP traffic, you won't block users from going to the website, but the AIM and Yahoo messengers will fail to work because you are restricting the TCP traffic needed to establish a connection. I believe if you look at the firewall config section of the Linksys router, you will be able to find which TCP port you need to block. Another good way of finding out is by actually loading AIM or Yahoo Messenger and looking at the network setting in them. You will usually find the IP address of the server they link up to as well as a TCP port. Once you find those, you can either block the TCP port, or block both the server's IP address and the TCP port it communicates on.

What we do in our network is block all TCP ports, except those we know we need. I suggest you find out which traffic your company needs to pass through en make rules to allow that traffic. Block everything else and gaming is over.

Some ports you may want to leave open:
21 - FTP
22 - SSH
23 - Telnet
25 - SMTP
53 - DNS
80 - HTTP
110 - POP3
143 - IMAP
443 - HTTPS

I'd block the rest.
