What kind of tool is this?
Mattermost is essentially a chat app that lets you exchange messages and files. Functionally it’s similar to the well-known Slack platform and can be used in any browser, via the mobile app (Android and iOS), or with the desktop client (Windows, Mac, Linux): mattermost.com
To join our community, you need an invitation from oose. Our goal is to offer a secure, GDPR-compliant space for exchanging professional topics, sharing ideas, and answering questions. The Mattermost server is run by oose, hosted in Germany, and operates under the Privacy Shield.
How do I sign up for Mattermost?
Your trainer will send you an invitation link. Use it once to register with your email address, first and last name, choose a username (firstname.lastname), and set your password. After that, log in simply with your email address and password.
Can I use Mattermost as a desktop or mobile app?
Yes. Download the app here: mattermost.com/install
In the app, enter this server URL: https://community.haqoo.com
How do I adjust my settings, and what should I configure?
Click your name at the top of Mattermost.
Under Account Settings you’ll find:
General
Full Name: Your first and last name.
Username: This is how you appear in the community (we recommend firstname.lastname).
Position (optional): Your job title or role.
Nickname: Your first name plus the initial of your last name.
Email Address: Visible only to you. Used for login, and can be changed here.

Notifications
If you don’t keep the community open all the time, choose how you’d like to be notified.
We recommend leaving “Words that trigger mentions” at the default, or at least adding: your username, @channel, and @all.
You’ll then receive an email when someone mentions you directly or the entire channel.
You can tweak these settings any time.
Display
Under “Team Member Name Display,” select Show First and Last Name to display full names.
You can also adjust time format, language, and theme here.
