Thats a bit convoluted, and of course, I'm only asking for the option to share a stack. Perfect example. I am currently the co-executor of a rather complex estate. Within my stack I have a host of notebooks, each having a unique purpose. I want my co-executor to be able to access all those notebooks without sharing each one separately. Anyhow, I still really like the product, and I'm learning new things about it every day. Thanks for taking the time to respond.
