After Showtime release, we were able to send a sim to another members game by the way of Simport. You have to be logged into your sims3 account, prior to playing your game. If you have a performer in your game, you can request a performer to come to your town, from another members game or you can send one from your own game. While in game, you go the three dots in bottom left and click on players wall and it should take you have an option to send or if someone has sent you a request, that will also be in there. You just hit "accept". It does, however take a few minutes for the game to send or for you to receive a sim, but you will get a message when it is finished. I hope I explained that right and it answered your question.
