After incorporating some feedback on member privacy, the Pumping Station: One Discourse is now public again.
The only publicly visible sections are Announcements along with a new Events subcategory. Any member can post into these and now they can be easily shared externally with non-members.
There is also a new Getting Started category that I hope new members will find helpful when trying to understand how to get into Discourse or other systems.
All historical announcements have been moved to an members-only archive folder to limit access to old discussions.
All discussions in Announcements and the associated subcategories will be public moving forward.
