SOLVED: How to upload Played Households to the Gallery?

If you created a family in Create A Sim, they should already be saved to your in-game library. All you would have to do to upload them would be to go to Manage Worlds, then click the Library button, connect to the online gallery (if you're not online yet), go into your personal library, click on the family you want to share, then click the little cloud icon. I did that with two households I made in-game and it worked perfectly.
