Hey plurals
So
Things are rough right now
A lot of us have been relying on SimplyPlural and Octocon for system information storage
We do have an alternative though
We've been using Foretelling, and really like it
It's meant for worldbuilding for writers, but we've been using the characters section for headmate information, worldbuilding section for headspace information, and the chapter section for journalling/communication/ect
There's a lot to it, and it's great for complex systems
It had tags and groups for sisasystems and alter sorting
And you can share the information to your trusted people by adding them to your collaborators (read-only, read and edit, ect)
It looks like this
