Thank you so much. This is exactly what I was looking for and I couldn't find it any where obvious on the main page. It wasn't clear to me what or who karrot was, and how it was related to self hosting. They might consider adding an additional 'about' button some where very obvious for dumb dumbs like me who just miss it.

Just before your post about Karrot I finally (re-)installed Agora on Yunohost as a collaboration suite. First few users onboarded and praying it works. It's a bit ugly but does the job. Karrot looks to be more map-focused than Agora from a very fleeting look, I don't think I've seen it in the Yunohost catalogue.
