Ektron Groups-au-go-go

I asked the Ektron twitter crowd - what's the difference between User Groups, Membership->User Groups and Community Groups? When to use which?

The replies from @billcava, @ajmarsland and @gandalf can be summed up in the table below.

	User Group	Membership Group	Community Group
Type of members	CMS users (content editors)	Membership users (site visitors)	Both CMS users and Membership users
Content / Folder permissions?	Yes	Yes	No
Useful for-	Workarea authorisation	Site authorisation	Blogs, forums, wikis, collaboration.
Where found in workarea	Settings –> User Groups	Settings –> Community Management -> Memberships –> User Groups	Settings –> Community Management –> Community Groups
