Alright, I set it to display the second argument, but it is displaying CHAT_MSG_CHANNEL_JOIN anyway. The second argument is the joining player, according to the wowwiki article.

"CHAT_MSG_CHANNEL_JOIN" Fired when someone joins a chat channel you are in arg1 seems to be empty arg2 Name of the player that joined arg3 seems to be empty again arg4 Number and name of the channel (e.g. "5. MyOwnChannel") arg8 Channel number arg9 channel name without number (this is sometimes in lowercase)

.lua

  local frame = CreateFrame("FRAME", "MParent");
  frame:RegisterEvent("CHAT_MSG_CHANNEL_JOIN");

  local function autoResponse(empty,joiner,emptyb,channel,number,nonmember)
    print("|CFF00FF00" .. joiner .. " has entered the channel.|R");
  end

  frame:SetScript("OnEvent",autoResponse);

Also, once I get the name instead of the.. whatever that is, can I just do this? Let's say I set the argument for the player's name to pname.

/script SendChatMessage("Welcome!" ,"WHISPER" ,nil ,pname);

Edit: Are all variables in lua global?
