Hey there! HumHub sounds pretty promising for what you’re looking for. It’s great that it has that Facebook group-style setup since it’s something a lot of people are familiar with. The community version being open-source is definitely a plus too. I’d say give it a spin and see if your family vibes with it.
Hey there! For a friendly and simple static site generator, you might wanna check out Jekyll. It’s pretty lightweight, works great with Markdown, and has a nice community. Plus, it’s super easy to deploy on S3. You can still hand-code if you want, but Jekyll will save you a bunch of time!
