I'm missing something simple here, when i run get-group | fl members i get the list of members in a group, but not all of them for large groups, the cmdlet returns a list of users and when it gets too long just completes with an elipses (e.g. user1, user2, user3, user4, user5, user6, ...). Any idea how to force it to list all members?

It looks like display limit on screen. You can save the result into a variable and can get the full list. $grp = get-group GroupName $grp.members | fl Name
