Seeing as I have a interest in collaborative communication platforms (reference to my last comment within the [Any opinions about Pydio?] (Any opinions about Pydio? - #4 by alefattorini) thread) and am fairly familiar with the NextCloud / OwnCloud project, I would like to help out testing Nextcloud integration with NS.
I have some free time tomorrow (and over the next 3 - 4 days) and will create a new VM containing a new NS installation solely for Nextcloud testing / development purposes.
