OK, I've registered MileageMonkey.net and set up DNS. Needed to know the IP to point it at and was about to ask when I realised one of the DNS history sites for slfft.org may have it (*). So www.MileageMonkey.net (and MileageMonkey.net itself) now points to 77.72.1.98.

SLF: hopefully it's just a simple web server servername change to get www.MileageMonkey.net working with MM as it was before the DNS expired. (i.e. with old data).

Thanks in advance for engaging with this again!

(*: Hey presto, months of patience to use MM and yep.... all along I needed to do was search for its old IP and point www.slfft.org in my hosts file at it. I have it back! Only for me of course but still).
