There are a couple of ways to send HomeBinder accounts to your clients. Ideally you want to have the "Binder Auto Transfer/Share" box checked off so binders will automatically deliver to your clients.
You can also send binders manually to your clients whenever you are ready to send it to them. You can send manually by clicking on the "Binder Options" drop down menu on the binder you want to send in your "Binders" Tab. Click on "Transfer" or "Share" to send the binder to your clients. To find out more about the difference between "Transferring" and "Sharing" Binders, see the "Settings Tab" section in the HomeBinder help center!
