How can you activate horses in Bella sara

you go to the homepage and follow these steps:

1) log in or create an account
2) scroll to top of page or activate the account if u just signed up( if u just signed up, u get a free horse to start with, but that is besides the point)
3)click on "Secret codes"
4) enter the code using all caps (getting the codes online wont work, considering people probably used them already)
