Can set a discord with a message timer so you can only post every now and then, to make more meaningful messages a requirement. Also a channel where all conclusions and information discussed on is saved that only you can post in is an option.

I'd like to see both options, so I'll just vote for the majority (again). Though Kato & Shumizu work very well together when it comes to Duel Runners, so it's probably them both working on them. Him doing the mechanical part, her setting up software, communications etc.
