I don't know about the Sims 3, but if you join the Synapticsims's website you can download some generic Na'vi customs made by the famous superhero sims guy himself. Sorry about the Sims 3 thing though. Maybe you can do something with these.

NO! I logged onto the Sims 2 Exchange today and the downloads were all gone! I even tried the foreign sites, but no luck! Can anybody help me out! I was going to download everything maxis made on the exchange but they were all missing! Can anybody help me with this, preferrably with the maxoidmoonbelly houses and Sims? Please!
