I need help with Sims 3 please?

There's a cheat that will allow u to add/remove sims to/from your home without having to mess with relationships. Press control shift c to open the cheat log. Then type testingcheatsenabled true. Then click shift and click on the mailbox with the mouse. That should bring up that selction and more. To turn the cheat off u open the cheat log and type testingcheatsenabled false. It should work :) I believe you can even summon sims to the lot with the mailbox cheat. Www.modthesims2.com has an entire list of cheats that becomes really valuable when it comes to making game play easier.
