I'd advise you to read over the rules and boarding specifications again.
-The max skills that a new horse can have is 30 over all
-Winnings should be left blank
-Look on the first page and there's a list of possible competitions that your horse can do. Choose some types of competitions for your horse to compete in.
-Breeding status is if you are allow other to breed with your horse or not. If you are letting people breed just type open and then how many credits you want to charge.
EDIT++
Here's the tack you wanted, Toppy.
Dressage:

Hunter:

All Purpose:

Western:

Hope these are alright. I haven't drawn tack in a long time. If you need me to re do the western one, I can. It's a bit awkward.
