I've just been doing some cleanup and incidentally came across this thread.

In case you aren't aware, we now have a Leantime appliance. Leantime is a more general "project management" tool (rather than being so software development focused).

As noted in the blurb on the appliance page: Leantime is a lean, open source project management system for startups and innovators. It's written in PHP, Javascript; backed by a MySQL (MariaDB) database. Designed to help you manage your projects from ideation to delivery.

So Leantime might be a better option for non-software related Project Management.
