You should read the reposted rules for the changes taking place with the farms effective 6:00am est on 5/24. We have reposted the changes in technical support under the thread: Farms - Reposted.
A couple notes about the changes: 1.To change your horses on the farm to in training select option 4 on your stable page, select radio button for training, and click update stable button at bottom. Any horses currently on the farm will need to have this done or their meters will no longer move towards 100/100. 2.The 90 day work rule and 75/75 meter rule are in effect immediately. The work time requirements will not be in effect until 90 days pass.
