ZTL Mattermost
What is Mattermost?
Mattermost is an open-source platform for team communication and collaboration. It works similarly to Discord or Slack, but is self-hosted by us and therefore independent of major third-party providers. At ZTL, we use Mattermost to exchange ideas, coordinate projects, and discuss topics related to the association—whether digitally or on-site in the space.
Mattermost supports:
- Text messages in channels and direct messages
- File attachments such as images, PDFs, or code snippets

Anyone can register and join the platform. ZTL members also receive access to protected channels that are invisible to non-members.

Channels
Channels are topic-based chat rooms. There are public channels that anyone can join, and private channels for smaller groups or specific topics.
- Public channels: Starting point for new members, e.g.,
#welcome,#ztl_vereins_termine, or#ztl_space_weristda. - Private channels: Reserved for ZTL members, e.g.,
#ztl_space_werkstatt,#ztl_space_besprechungsraum, or project-specific channels.
