How to talk l33t

I'm introducing the language of 'L33T'.
'L33T' is an online made up language that is made up of replacing the letters in a word with numbers it was created in the 80's for hackers to get past FBI keyloggers. A simple example sentence is;
1 4m 50 1337, 1 0wn j00

Although the language would be frowned upon by adults in this day and age its still used to many children on the internet mainly people who play video games or use AOL as an ISP(Internet Service Provider). No one knows the single person who made it up or where it was made up, but as tyhe internet grows older the language is still being used and most likly will be used for many years to come.
