if CLIENT then
function WarnMenu()
local f = vgui.Create( "DFrame" )
f:SetSize(ScrW()*0.277,ScrH()*0.138)
f:SetTitle("Birbs Warn Menu")
f:SetVisible(true)
f:SetDraggable(true)
f:ShowCloseButton(true)
f:Center()
f:MakePopup()

local WarnList = vgui.Create( "DListView", f )
WarnList:Dock( FILL )
WarnList:SetMultiSelect( false )
WarnList:AddColumn( "Player" )
WarnList:AddColumn( "Warns" )

for k,v in pairs(player.GetAll()) do
WarnList:AddLine(v:Nick(), v:GetWarns())
end

WarnList.OnRowSelected = function( lst, index, pnl )
     print( "Selected " .. pnl:GetColumnText( 1 ) .. " ( " .. pnl:GetColumnText( 2 ) .. " ) at index " .. index )
     local playerName = pnl:GetColumnText(1)
end
end
function WarnChat(ply, text)
hook.Add( "OnPlayerChat", "NocoolWarns", WarnChat)
if (string.lower(text) == "!warns" ) then if CLIENT and table.HasValue(AccessToMenu, ply:GetNWString("usergroup")) then WarnMenu()
