Can you change group names?

[Rob Huntsman]

I was wondering if big groups with 1k+ members was it possible to change the group name with out everyone moving over.

As far as I know, no.   Group names can only ever be used once.  So I would assume that that also means that they can't change.   I've never seen it happen and I've been around for over 10 years.  Seriously though it's not that difficult to migrate members to a different group.  Create the group invite your list members (yes it will be time-consuming) that also send notices everyday or every other day to let stragglers know of the change.
