Microsoft's guide to computer slang

Over at the Microsoft website, parents can learn how to understand leet, a popular computer slang that is used by kids today. From Microsoft:

Numbers and symbols often replace the letters that they resemble. The term "leetspeak" could be written as "!337$p34k". The character "!" replaces the letter L, "3" poses as a backwards letter E, and "7" is the letter T, and so on. Other examples of character/letter replacement include using "8" for the letter B, "9" for G, and the number 0 for the letter O. The substitution is limited only by the leetspeaker's creativity.

Letters can be substituted for other letters that might sound alike. For example, the letter Z can replace the final letter S in the word "skillz". With the letter X replacing the letter C or K, the example becomes "sxillz". Then using numbers and symbols, leetspeakers might refer to their computer skills as "5x1llz".
