Simple but ..

PHP код:

  new ID,
       Message[256],
       String[256],
       String2[256];
   if(sscanf(parmas, "us[256]", ID, Message)) return SendClientMessage(playerid, COLOR_RED, "Usage: /pm [id] [message]"); 


You kidding right? Why size 265? Don't ya think it's too much?
Also, You don't have to define a two variables for formatting, only one define is enough for +10 tho.
I can't show all the codeshere, since i'm using my phone. But try to optimise it a little bit more.
Good start though.
