I found somthing that works for terran thats really easy to use at the start when you are teching up you only need to build 6 supply depots and use the extra supply from the orbital command and you will be good for a while, i usually build 2 supply depots at the entrance to my base to block it off and then build 4 in the base probhably at the back it works damn well for people who forget to build depots like myself.
