Hope this is what you mean:

On Top

pawn Code:

new Text:abc;
new msg;

OnGameModInit

pawn Code:

abc = TextDrawCreate(3.3750, 430.0, "/commands");
  TextDrawTextSize(abc,629.000000,2.000000); 
  TextDrawAlignment(abc,0);
  TextDrawFont(abc,2);
  TextDrawLetterSize(abc,0.499999,1.399999);
  TextDrawColor(abc,0x00FF00FF);
  TextDrawSetOutline(abc,1);
  TextDrawSetProportional(abc,1);
  TextDrawSetShadow(abc,1);
  SetTimer("cmdsc",1500,true); // Messages changes every 1.5 sec

OnPlayerConnect

pawn Code:

TextDrawShowForPlayer(playerid, abc);

At the end

pawn Code:

forward cmdsc();
public cmdsc()
{
switch (msg)
  {
  case 0:   
    {
     new newtext[41];
     format(newtext, sizeof(newtext), "/help");
     TextDrawSetString(abc, newtext);  
     msg++;
    }
  case 1: 
    {
     new newtext[41];
     format(newtext, sizeof(newtext), "/register");
     TextDrawSetString(abc, newtext);
     msg=0; // this must be the last!!!
    }

  }
}

Should work.
Hope I helped.
