They are not free you need to know its a mirror of SL and uses real money so you need to be aware of this they do give you a limited amount to start with and ways to make a little but not enough to rent a week is $100 of their coin so in the end you need to either make more or get more from your bank account they are not upfront like other places and they are not opensim its private like Second Life you cannot hop there and out. So be warned Not very helpful and the islands are not to the ocean they are small. Would not recommend this grid.
