Admin message addon to server

[Fixed]

Hey, I want a addon to the server so I can like yell so every can hear it like: Propblocking is not allowed
I want to do like this in chat:
/adminyell <message>

Also a message where players can send if you will report a player, the message should arrive to the admins.
/report NAME is propblocking, teleport to me please.

Hope you understand me!

Ulx and such administration mods already have these functions. If you got a admin system that allows teleportation and such, you most likely have the ability to do a "yell" (appear on middle of screen or in chatbox). Just look through the commands.

Thank you, but I still need the report thing this is my code I make for admin yell:

function AdminAdvert(ply, args)
if args == "" then return "" end
local DoSay = function(text)
if text == "" then return end
for k,v in pairs(player.GetAll()) do
local col = team.GetColor(ply:Team())
TalkToPerson(v, col, LANGUAGE.ADMIN ..ply:Nick(), Color(255,0,0,0), text, ply)
end
end
return args, DoSay
end
AddChatCommand("/adminadvert", AdminAdvert)

How can I make so only admins can see this?

Uh, would it not be best to use ulx or something like that as a base? They got "adminchat" which sends a message to all admins, anyone can do it but only admins can read it.
