Joining the test server
If you’re thinking of joining Mattermost as an open source contributor, as an employee or staff contributor, or as an ecosystem partner, we welcome you to start an account on our server and see what it’s like to work here–and even try installing the mobile apps if you would like.
A bot will suggest different channels for you to view, and you’re welcome to join any channel on the server. All the information you’ll have access to is public (employees and staff have confidential channels and workspaces on the server).
Say “Hello”
If you’re in contact with someone with an @mattermost.com email address, such as a recruiter or hiring manager, you can message them or your hiring manager on the server by contacting them at firstname.lastname to let them know if you have joined.
Try some formatting
To practice sending messages in Mattermost, particularly around formatting, you can send messages to yourself to test out how messages will look before sending to another person.
