Yes! We made Zube Tickets so support teams and non-technical people have a place to report problems/questions. The cool thing about Zube Tickets is that they automatically track what the development team is working on and notify you when things get done. This makes it easy to know what's going on without having to understand the technical details of every GitHub issue!
At the moment, you need at least read access to the repo to use Zube but we're working on allowing email only login for non-technical people to use tickets and view the Zube board. We're aiming to have that out in a few weeks.
