	if (not normalMessage) then -- it's not normal message
		return false -- do not continue
	end

	local playerName = getPlayerName(source)
	local playerX, playerY, playerZ = getElementPosition(source) -- get position of player who sent the message
	local playerInterior = getElementInterior(source) -- get interior of same player
	local playerDimension = getElementDimension(source) -- dimension as well
	local nearbyPlayers = getElementsWithinRange(playerX, playerY, playerZ, chatRadius, "player", playerInterior, playerDimension) -- get nearby players within given radius
