Issue templates would be good
In order to encourage people to write good issues, we should consider providing one or more issue templates.
In https://third-bit.com/2021/01/18/how-to-write-a-memo/ is contained a good description of how to summarise to persuade. It might be good reference material for producing issue templates.
We should get the templates in place before we consider opening subplot to a wider audience to ensure any subsequent issues are well formed.
