I see the confusion
So this is the workspace (Open Care Research group, as in research team workspace), where coordination happens and a lot of the content is work in progress.
https://edgeryders.eu/en/op3ncare-community should not link to the group discussions, but directly to the Community Home (more curated). The Op3nCare community discussions should be less accessible, to focus only on content in the group that is gathered under Challenges. Responses to challenges are the main conversation threads rather than the group posts as you know them.
We need to redirect the link to Community Home also from the Projects page, to avoid landing on https://edgeryders.eu/en/op3ncare-community
