How do you get another breed tab for your page on Howrse?

When you have reached 3 karma points, put your cursor over the "Directories" tab at the top of the page and click on "Breeding". Then it will take you to another page. At the top of that page should be two buttons saying "Manage my breeding farms" and "The last breed variations". Click on "Manage my breedings farms" and you should be able to do it from there!

Hope I helped,
