How to DEMO?

I know this might sound dumb but...how do you demo someone? I caught this guy being very suspicious (his crosshair would have recoil but it would always come back to the person's head), but anyway. I just wanted to know how to demo someone and post it somewhere like fourms or something. After all, when I play in this server, I rather play with legit players than hackers. Thus, playing with people with like string shot, speed, and poison is bad enough.

record (name) - record the demo

stop - stop demo

playdemo or viewdemo (name) - to watch

Also you name it when you do record. So like record hacker.dem or something like that. And then playdemo hacker.dem to watch it.

u dont need .dem in it

just record hacker

playdemo or viewdemo hacker

.dem is automatic

Oooh cool. Didn't know that
