Ok, here we go! As promised, I am very happy to be able to point invested Mozillians at the test instances of our candidate synchronous messaging stacks.
Our Rocket.Chat test instance is here: https://rocketchat-test.allizom.org/
Our Mattermost test instance is here: https://mattermost-test.allizom.org/
Our Matrix/Riot.IM instance is here: https://mozilla-test.riot.im/
On each of these servers, we’ll be taking feedback in the #synchronicity channels on each of those services, as well as in this thread. And, of course, you can always email me - firstname.lastname@example.org - directly.
Let’s give this stuff a shot, see how it works for us!
