Ok cheers.  No on the OCA.  I don't have direct access to a printer or 
scanner so I will have to run around to sort it out but I have plenty of 
spare time so will chase it up (assuming covid hasn't closed everything).

I can't see how this particular change includes any copyrightable 
creative input but I suppose that's up to the project to decide.

Regards,
