Click on TOM top right hand corner......
On this page find the register for TOM button and register.
After you have done this you are ready to upload horses. You would have needed to have exported your horses whilst playing your game using the E button located on the menu when you have one of them selected in your game, Once you have enough horses exported you will need to trial them to find what is your best horse over each distance using the RACE BUILDER, once you have discovered the horses you wish to enter you upload the file to TOM.
Any more questions post them in this thread and someone will explain what to do if you are having trouble at any point.
