Ok...you code freaks!! Ive read quite enough posts with your vague references to l33t this, or w00t that...or come to think of it...the very name f00.

So...I decided to do something about it...seeing as how we all live in this Al Gore inspired world. Here we go.......

Here is the official wikipedia definition
Leet (often l33t, 31337, Leek or 1337) is a coded, or simply a novelty form of English spelling. It is characterized by the use of non-alphabet characters to stand for letters bearing a superficial resemblance, and by a number of quasi-standard spelling changes such as the substitution of "z" for final "s" and "x" for "ck". It is often used on the Internet by hackers, crackers, script kiddies and gamers. Even lamers are beginning to pick up parts of it. Some hackers do not use l33tspeak due to its association with Internet users whom they dislike.

I even found a downloadable translator.
