I have a Forms Based Authentication site that has a user management
webpart. This needs to get the groups from the current site collection
to let the administrator assign users they are creating to an initial
group. Currently the code gets all the groups from the current SPWeb
that the webpart is activated on using the AssociatedGroups, but I need
to expand that to all the groups in the site collection. Can someone
give me a clue as to where to begin with this?
