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/
- Documentation: https://docs.mattermost.com/index.html
For IPMB Users:
- The email module is not enabled, so “Forgot your password?” is not functional. Ask your lab PI or the IPMB IT office to reset your password if needed.
- The storage space is limited. While it is possible to upload files to facilitate communication, please be careful with large files; sharing via external links or delete the files after discussion is recommended. Remember, this system is designed as a messaging platform, not a file-sharing service.
