Show history of own registrations

[ReneB]

I am not entirely convinced that we cannot open registrations before this feature is done. It might only be required for cancelling and/or to look up information that you should already have obtained through other means. Cancelling, however, can - for now, possibly forever - also be done through mailing the organisation.

This has been already implemented a long time ago, closing.
