Richard has posted a really nice article, but sadly in the question field alone.
I tried to guide him through the process of answering his own question, but that didn't work out – he deleted the question, all my praise for its content nonwithstanding.
- revive that question
- split the answer-content from the question into an answer
- make it so that Richard at least can get part of the reputation this answer (and question) deserves and
- let Richard know he was absolutely welcome to post this, and that the conversion to Q&A format is really just a formality?
