www.amxmod.net Amx is basically the same as Admin Mod but you can add more plugins to it. My cs server have so many plugins:
Superhero Mod (with 9 superheros that I made)
Blackjack
Vexd Utilities
fake death messages
amx_slay2 (I can slay people via lightning bolt/blood/or make them explode
)
Fireworks
Musical radios
2 different forms of disco mode
Walls to block off parts of maps I dont like
Verdict: w00t for AMX Mod!
