With the Buddy List, you can find out the User ID of any user on Teamliquid! The User ID is basically a number that indicates when that user first registered on TL. For instance, Waxangel was the second user to register on TL, so his User ID is 2. Liquid'Meat, the founder of the site, has his ID as 1, and so on.
While this doesn't really have much practical use, it's pretty cool to see when the veterans of the site first appeared. You know, legends like mensrea, Saro, Manifesto7, travis, and those other handsome fellows. You can also find out your own User ID with this trick.
Here's how you find out someone's User ID. Handy-dandy images are included for your convenience. Since I'm a retard and don't have Photoshop or MSPaint or anything, I can't highlight the appropriate sections of the website, but I'll do my best to make it clear what you gotta do from screencaps.
