Adding char names to addon via slash command

[Believe82]

Hi so I have addon that helps me distribute mounts and loot in aq40 and I would like to create an exemption table using a slash command.

At the moment I call the slash command via:

SLASH_NLOOT1 = "/nl"

SlashCmdList.NLOOT = function(input)
	input = string.lower(input)
        if input == "log" then
		NL_LOGGING = not NL_LOGGING
		local word = "Disabled"
		if NL_LOGGING then
			word = "Enabled"
		end
		print("NLoot: Logging " .. word)
		return
	elseif input == "resetmount" then
		mountList = {}
		lootList = {}
		mountDistributed = 0
		print("NLoot: Mount list and all history have also been reset")
		return
	elseif input == "history" then
		local lootCount = 0
		for i,v in pairs(lootList) do
			print(i .. ": " .. v)
			lootCount = lootCount + 1
		end
		if lootCount == 0 then
			print("No items have been distributed yet")
		end
		return
	elseif input == "masteraq" then
		NL_Master = true
		local playerName = UnitName("player")
		SetLootMethod("Master",playerName,"1")
		return	
	elseif input == "master" then
		NL_Master = true
		local playerName = UnitName("player")
		SetLootMethod("Master",playerName,"2")
		return
	elseif input == "" then
	else
		print("NLoot: Invalid Command, Input '/nl help' to get a list of available commands")
		return
	end

	if NL_ENABLED then
		NL_ENABLED = false
		print("NLoot: Disabled")
	else
		NL_ENABLED = true
		print("NLoot: Enabled")
	end
end

I wonder if I can add a slash command "/nl hasmount Playername"
where the lua would handle the Player name and pass it to an array or table. this way I could then make the addon check if the player is on that list or not.

Thank you for your help.
