Lol, wouldnt it be easier like this?
if(GetPlayerName(playerid) == your name)
SendClientMessageToAll(0xFFFF00AA, "The server owner has joined to the server.");
else
new n[MAX_PLAYER_NAME], string[48];
GetPlayerName(playerid, n, sizeof(name));
format(string, sizeof(string), "%s has joined the server.", n );
SendClientMessageToAll(0xFFFF00AA, string);
