@msbt I can help test if needed. I use webhooks to filter by keyword and aggregate news articles, forum threads, etc.
The matrix server and riot app work great so far! Just needed a bump in memory limit when exploring the channel list from matrix.org
Recently moved from mattermost -> rocketchat and now excitedly waiting for matrix to go live in the Cloudron app store. Please let me know if there's anything I can do to help!
