Message Bank Usage

Hi

Has anyone implemented the message bank functionality in particular in the UK and if so what are your experiences of it in particular for custom messages? We are thinking of using it as our long term store and would like any feedback on it. We use a mix of REST web services, custom messages, HL7v2 and FHIR messaging within the Health area (NHS Trust to be exact).

I would also be interested in which version you implemented this upon.

Thanks

Ian
