Group Chat

Intro

Group chat tools (e.g., Slack, Discord, Mattermost) can be highly effective for team communication
- Concept: a platform for work-related communication; no notification outside of working hours.
- Email: for external and formal communication
- Real-time message (e.g., LINE, phone): reserved for emergency and messages that require real-time response. Limit the usage.
Mattermost is an open source option that can be self-hosted. This is attractive in terms of information security/privacy and cost.
- App (Android/iOS/Linux/macOS/Windows): https://mattermost.com/apps/
