Overview of Mattermost

  • Mattermost (MM) is a messaging system. All XRNL activists are expected to be on MM.
  • Activists can use any username (like @Fred_Amsterdam or @JimForTheClimate), so a certain level of privacy is possible. You do have include an email address when you register, though that is not visible to other users.
  • On joining you will be made a member of a particular "Channel". Channels are set up for types of activity, particular locations, and for once off events. More on Channels below.

Channels in Mattermost

  • Most channels are done in English, some where most posts are given in both English and Dutch, and other channels Dutch only. The convention for which language is Still-finding-out.
  • Channel types with (clickable) examples
  • Public vs Private Channels
    • Most Channels are public and so readable by all MM users - in practice that implies information is accessible to the whole world. There are activities which require messaging to extend to a small group of people - and that is when a Private channel is appropriate - you may receive an invitation to join a Private channel, which will then come up in your MM Sidebar.

Direct Messaging

  • You can also message an individual or a small group (up to eight users) for a conversation which does not fit into the mould as a Channel. Direct Messaging usage works much the same as WhatsApp. Ask your XR colleagues what is their ID on Mattermost.
