@DrFrostMaths Hey Jamie! Nice to have met you yesterday. It's pure chance that I saw your follow, I almost never open this site, and don't have it on my phone. I now spend all my time on Mathstodon.xyz ... feel free to join us there, and ask any questions. Or email me.
I have a note in my diary to ping you today, but I think this is my only way to contact you. I'm basically never here now ... find my on Mastodon or email.
