I just stumbled on https://github.com/cotech/website/issues/18, which is an issue raised on the issue tracker for the CoTech website repository about including a link to a news/blog feed and the possibility of including a newsletter, if they are made.
As far as I know, there is no existing newsletter. Does anyone want to join in to make this? I’m keen.
Also, I know a bunch of people are blogging and maybe they are blogging about CoTech, so instead of trying to make a bunch of new content, we could aggregate coop blogs, or coop member blogs (if they are cool with that) and just let people have an overview of all the different opinions from there.
