Yes, indeed. So many things to do, and all at the same time.
Everything you might want to know about the New Linden Homes is on the brand new wiki at http://wiki.secondlife.com/wiki/Linden_Lab_Official:New_Linden_Homes_2019 and in the covenant, which you can read in About Land. The Knowledge Base article will be updated very soon. As long as we still have the Old Linden Homes, though, it's bound to be a little confusing. As you can see, we are still rolling out some features and making some adjustments that had to wait until after the new regions were open to the public. Refer to the wiki when you have questions about the New Linden Homes, and be prepared for updates there as Belliseria evolves.
