Nice! I’ve always wished for more seamless integration between discourse and nextcloud, which I use for my family site. What I really miss is the ability to easily talk in discourse about files on nextcloud, e.g. a photo or pdf.
I set up single sign on using the social login nextcloud app. This lets me map discourse groups to nextcloud groups to give different classes of people access to different nexcloud folders. If the account doesn’t already exist in nextcloud it is added automatically when they first sign in via my discourse site.
