Jack Linden has announced on the official Second Life blog that the prices for Openspace/Void sims are going up because they are burdening the grid's resources beyond expectations.
This group is for snapshots from Openspace/void sims to show Linden Lab what content creation, free enterprise, and inspiration they may be losing when they price these builds and residents out of ownership.
(It would be helpful to put the name of the sim in the description of the photo as well as adding it as a tag in case any bloggers want to do a tour of these sims as part of a travelogue.)
