Are group_types useful for granting a user (or group of users) specific privileges to all instances of a package-key?
Here's a use case I need to consider:
There are N subsites, each subsite represents a company department, project/program or warehouse etc. The function of handling accounts payables (vendor invoices etc) are handled by the same people regardless, so they need access to a certain part of each subsite, but not the other parts.
Maybe the way to handle this is to give them their own subsite and access via some kind of grouping in parameters..
