This Forum has a neat integration with Telegram. You can receive personal notifications and reply to posts right from the telegram bot. It allows for a nice hybrid approach to communication - asynchronous in time of peace, synchronous in times of need 
To set it up, follow these steps:
- Write any message to this bot. It will reply with your unique chat ID. Copy that ID
- Go to your profile settings, scroll to the bottom of the page and paste the ID into the “Telegram Notifications” field. Press “Save”.
Done! You should now receive notifications from the bot and be able to reply to them from your telegram app. Your replies will show up in Forum.
