Sharing Dashboards post-popup questions

Thanks for the Sharing Analytics popup, Chris. We couldn't attend the live presentation but having watched the recording, now have a few questions:

• If the owner of a a shared dashboard subsequently moves it into a different folder, renames it, or adds viewers, will the "republish" trigger notifications to all the existing viewers?
• I understand we can't share entire folders of dbs, but do the owners' folders have any impact on how the dbs are displayed for users? Or do users just see a list of dashboards without folders?
• Is there a way for db owners to quickly see which of their dbs they have shared? We're using a naming convention for that now but is there a better way?
• Is there any way for viewers to delete shared dashboards that are no longer of interest to them? Or do they need to contact the owner for that?
