Is it available or is it possible for SL to create a 2nd permanent inventory (empty) for customer? This would be ideal for sorting and cleaning. I have been on sl for so many years and now have over 90,000 items that I need help cleaning up. The ability to clean an inventory using this tool would be most helpful. Does anybody have ideas for fast, efficient inventory clean up? Reducing duplication or very old high prim objects without having to rez everything etc.groan
