You've got to store somewhere each line's text and the text order. When a player connect it sets the first line (Textdraw ID stored at [0]) and then raises the internal order count. The next player that connects will get it at [1] and so on until it reaches the third array ([3]). If that happens then a descending loop will move whatever it was from line 2 to line 3, from line 1 to line 2 and from line 0 to line 1. Then it'll proceed to put the new text on line 0. I haven't tested this.
