Everything takes longer than expected these days. Cyan Worlds plans are to move MO:UL to open source, and we finally have some good news. We've taken a first step and started a MO:UL server, so the Ages of Uru are available again. We've opened all the Ages, and added most of the goodies in MO:UL. Were referring to it as MO:UL again - feel free to explore and enjoy.
And the cost is pretty good. Free!
