The CMNO course is due to be retired at the end of the year, I would just wait and book a seat on its replacement.
What @BlakeRichardson said for sure.
But, if you can't wait for any reason I'd start with emailing firstname.lastname@example.org. If they can't help you they should be able to point you at those who can.
Its certainly worth getting this CMNO moved over as it has become ECMS1, you will then be in the best position to sit ECMS2
At the end of the year the new certification based on these two should be ready
