BlueCoat manufactures security devices providing Web Content Filtering for corporate enterprises. They also make a parental control application called K9 Web Protection which is free for home users. It is an excellent balance of filtering capability and ease of use and has a lot of options to help parents set limits on web browsing and block unsafe or inappropriate sites. What you get is pretty impressive, given that it is free.
Whether you’re working on code, content, design, usability and business processes surrounding website development, you should stop by A List Apart. I’ve used several excellent CSS tutorials from this site and I highly recommend it.

How many routers does RIP support? How about RIP version 2? I see that your tutorial says 15 hops, but does that mean you can only have 15 routers in your network?
