Chatstats cmd for Masters only

[Madman]

Hi i use this chat stats script
Great script =)

-- chatstats v2
-- by tezlo
-- modified by tezlo and Optimus
-- modified by Madman for his "needs" :p


--everybody can.. 
--?mystats 
--?userstats  
--?stats [category] (there are 4 categories.. posts chars --words smilies) 

--OPs also can.. 
--!savestats and !loadstats (obsolete.. stats get saved --automatically) 
--!clearstats

eyes = ":;8B="
nose = "-o'"
mouth = "%[%)%(%]DpP"
-- modify the above to fit your needs!

stats = {}
names = { posts = 1, chars = 2, words = 3, smilies = 4 }
-- can you think of something else to count? post up


function Main()
	loadStats()
end

function OnExit()
	saveStats()
end

function DataArrival(user, data)
	if strsub(data, 1, 1) == "<" then
		local s, e, str = strfind(data, "^%b<> (.*)%|$")
		local s, e, cmd, args = strfind(str, "^([%!%?]%a+)%s*(.*)$")
		if s then
			cmd = strlower(cmd)
			if cmd == "?mystats" then cmdStats(user, user.sName)
			elseif cmd == "?userstats" then cmdStats(user, args)
			elseif cmd == "?stats" then cmdTopStats(user, args)
			elseif cmd == "!savestats" and user.bOperator then saveStats(user)
			elseif cmd == "!loadstats" and user.bOperator then loadStats(user)
			elseif cmd == "!clearstats" and user.bOperator then clearStats(user)
			else return end return 1
		else	updStats(user.sName, str)
		end
	end
end

function cmdStats(user, target)
	local tmp = stats[target]
	if tmp then user:SendData(">>> chatstats for "..target..": "..tmp[1].." posts "..tmp[2].." characters "..tmp[3].." words "..tmp[4].." smilies")
	else user:SendData(">>> no record for "..target) end
end

function cmdTopStats(user, args) 
local id = names[args] or 1 
local index = sortStats(id) 
local chat = "" 
chat = chat.."\r\n\r\n\t============== -=Current Top 20 Chatstats=- ==============\r\n" 
chat = chat.."\tNr:\tPosts:\tChartrs:\tWords:\tSmilies:\tNick:\r\n" 
local n = getn(index) 
if n > 20 then n = 20 end 
for i = 1, n do 
local nick = index[i] 
local tmp = stats[nick] 
chat = chat.."\t"..i..".\t "..tmp[id].."\t "..tmp[2].."\t "..tmp[3].."\t "..tmp[4].."\t"..nick.."\r\n" 
end 
SendToAll(chat) 
end 


function loadStats(user)
	stats = dofile("chatstats.dat") or {}
	if user then user:SendData(">>> Stas Loaded") end
end

function saveStats(user)
	local f = openfile("chatstats.dat", "w+")
	assert(f, "chatstats.dat")
	write(f, "return {\n")
	for nick, table in stats do
		write(f, "\t"..format("[%q]", nick).." = { "..table[1], ", "..table[2]..", "..table[3]..", "..table[4].." },\n")
	end write(f, "}") closefile(f)
	if user then user:SendData(">>> Stats Saved") end
end

function clearStats(user)
	stats = {}
	if user then user:SendData(">>> Stats cleared") end
end

function sortStats(id)
	local index = {n=0}
	foreach(stats, function(nick, tmp) tinsert(%index, nick) end)
	local f = function(x, y) return stats[x][%id] > stats[y][%id] end
	sort(index, f) return index
end

function updStats(nick, str)
	local tmp = stats[nick] or {0,0,0,0}
	tmp[1], tmp[2], tmp[3], tmp[4] = tmp[1]+1, tmp[2]+strlen(str), tmp[3]+cntargs(str, "(%a+)"), tmp[4]+cntsmilies(str)
	stats[nick] = tmp
end

function cntargs(str, rule) 
	local s, n = gsub(str, rule, "") 
	return n
end

function cntsmilies(str) 
	return cntargs(str, "(["..eyes.."]["..nose.."]?["..mouth.."])") + cntargs(str, "(["..mouth.."]["..nose.."]?["..eyes.."])")
end

It allows The Ops to Save and load stats...
But i want it to only allow masters to load and save stast
Can anyone help me?

replace the dataarival function for this 1.

function DataArrival(user, data)
	if strsub(data, 1, 1) == "<" then
		local s, e, str = strfind(data, "^%b<> (.*)%|$")
		local s, e, cmd, args = strfind(str, "^([%!%?]%a+)%s*(.*)$")
		if s then
			cmd = strlower(cmd)
			if cmd == "?mystats" then cmdStats(user, user.sName)
			elseif cmd == "?userstats" then cmdStats(user, args)
			elseif cmd == "?stats" then cmdTopStats(user, args)
			elseif cmd == "!savestats" and (user.iProfile == 0) then saveStats(user)
			elseif cmd == "!loadstats" and (user.iProfile == 0)  then loadStats(user)
			elseif cmd == "!clearstats" and (user.iProfile == 0)  then clearStats(user)
			else return end return 1
		else	updStats(user.sName, str)
		end
	end
end
