Hi
I've been using TeX for over 30 years, for mathematical writings. For about 15 years I worked at the Open University, mostly as the LaTeX expert supporting and developing the use of TeX for the production of course materials (for distance learning).
From 2006 to 2010 I was Chair of the UK TeX Users Group. Here's my final report.
I'm now retired, which give me time for math research, Python, TeX and other interests.
Since December 2020 I've been running a TeX Hour, every Thursday 6:30 to 7:30pm UK time. Here's the zoom details (which may change later)
Meeting ID: 785 5125 5396

Happy TeXing
