While the Self-Registration works great, here is something that's required AFTER Readers have been allocated to one or more Reader Groups via self-registration:

It would be extremely useful to be able to assign or remove Reader Groups to/from all readers with a particular domain name. Especially with a growing number of Readers.

For example, if all existing Readers with domain example.org are assigned to Reader Group A (as arranged via Self-Registration), and they should now ALSO be assigned to Reader Group B, then it would be great to be able to do that at once, rather than going back to all of the individual Readers.

As it works now, adding Reader Group B to the domain example.org would only affect newly signed-up users, however all existing ones remain linked to Reader Group A only.

Hope this is clear - please let me know if more explanation of the issue and request is needed.

Thanks for considering!
