[Exchange] Question on allowing users to modify distribution lists

[Maglinger, Paul]

 I just moved some more users over to Exchange 2010 and they have lost the 
ability to modify the distribution lists that they used to.
I have read several articles on assigning the MyDistributionGroups and 
MyDistributionGroupMembership and it mentions that it will allow them to 
"manage some of the properties in groups that they own".  
By "owning" the group, is this the same as the user specified in the "Managed 
by" window in the group properties, group information tab?
