I am trying to set up my dividers between my foals and my aged horses how do i set them up how I want them?

To put dividers in a certain order you go to: Home > Edit Profile 

Then scroll down until you see the "Manage Dividers" heading. Under that heading should be a list of all your dividers (first, make sure you've selected "yes" in the "Use Dividers:" option a little bit above the "Manage Dividers" heading). 

This is where you can edit your dividers. You can change the names, delete them, and choose which order they go on your page. 

To edit the order, just number them in the order you want on the left side. E.g.: If you want "Foals" divider first, put 1 in the box and then put 2 in the box for "aged horses"

Also, (just in case you need this info) any store bought horses or newborns will be placed below all your dividers and you will have to go to each animal's page to put them in the divider you would like (this is the "None" divider).

Aaandd just in case that was confusing here's the help page on dividers (scroll down a ways): here
