This is the suggested way to create a post when reporting a hacker in this section of the forums.
The Subject of the topic should be the player's name.

Name/B3ID:

Use !lookup playername to get the b3id @xxxxxx.

Time/Date:

Rough time in est, use !time ingame to get this.

Type of Hack:

(Aimbot, Wallhack, General being annoying.)

Server:

(CTF, JUMP, BOMB)

And attach the demo of the cheater please.

Well all we really need is the name and which server it was on. The rest just makes it much quicker for us.

Ahh, now I remember. Your site admin again.

When you create a demo, you can type "demo" in the console, or you can type "demo demoname" to make the resulting file be just "demoname.dm_68" instead of that long string of information that is the default filename. This may make it a little easier for folks to download from here and view on their systems...
