imvu lite is risky for now, i wouldn't use it for now.
Also the greeter program does not allow any more greeter for now. the "cheapest" way to get your guest_ out of your account is to take a marriage pack when it's in sales, it was around 17$ earlier, and it register the name for both accounts + it has a shared rooms, it's not free but if you can share the cost with someone when it's in sales, it's actually a good deal
