How to add callout things...

So I was playing on my new server and I was wondering, how do I make it so it says things in chat like “sign up on the forums at (blah blah)!” I was wondering who knew how to do this because I did some research and can’t find anything… Also I’m using NFO server…

ULX can do that. I can’t remember how, though.

timer.Create( "asd", 400, 0, function()
    for k, v in pairs( player.GetAll() ) do
        v:ChatPrint( "asd" )
end )
