2. Then go to left4dead2 => addons => sourcemod => configs => admins.cfg.

3. Scroll down to the end of the script until you find:

Admins
{

}

4. Now you need to input your info in this format:

  "PlayerNickname"
  {

   "auth"  "steam"

   "identity"  "insert_players_steamID"

    "flags"  "z"

    "immunity"  "99"

  }

  { 

   "auth"  "steam" 

   "identity"  "insert_players_steamID" 

    "flags"  "z"
