Is your feature request related to a problem? Please describe.
We'd like to populate the blog with more content, and we have fortnightly update emails that have been shared with the company's volunteering group over the past year or so. From the first of these updates, the stated intent was to make them public. The blog seems like a good place to put them.
Describe the solution you'd like
Describe alternatives you've considered
For a long time, an alternative plan to migrate to a 'public to everyone' mailing list was considered. This may still be a good idea; it works well for a lot of free and open source projects. However there is a lot of careful infrastructure arrangement to consider, as well as moderation and safety considerations.
Given that we have a web-based blog already available, this is a good way to allow more people to read about the project, even if it is less interactive than might be ideal in the long-term.
