News Server

Ok It's me with this problem:
I want to set up a news server which sends Messages to the clients, which should be shown on the screen.
It's running quite well, but after some seconds on the screen there is always '%getNews%..news'
Here is the clients code:

term.clear()
term.setCursorPos(1,1)
rednet.open("top")
print("Reader is only waiting for updates")
sleep(1.5)
term.clear()
term.setCursorPos(1,1)
while true do
event, param1, param2 = os.pullEvent("rednet_message")
if param2 == "exit" then
  break
end
print(param2)
sleep(1.5)
end

Any ideas how to prevent it from being shown?

Well, the problem must be in the server, since that code has no errors. The only thing I would change on the client is making it receive only from the server, not every computer. Something like:

local serverID = 0 -- change to the id of the server

-- print message and open rednet, etc.

while true do
  local evt, id, msg = os.pullEvent("rednet_message")
  if id == serverID then
	if msg == "exit" then
	  break
	end
	print(msg)
  end
end

It looks like your error has something to do with concatenation. Perhaps you forgot a ")" on or around that line?
