Inspired by the earlier conversation, “Integrating Fedora Matrix homeserver with discourse-chat-integration plugin?”, I wipped up a small script to display an RSS feed and packaged it as a container: Overview - rss_widget - Pagure.io.
How would I go about getting my custom widget added to the Fedora Magazine room? Would the Fedora Project host such a container?
Thanks. 
Here is a preview of what the widget should look like:
It is very simple. It doesn’t auto-refresh. I’m not sure how I would do that. I guess I would need to add some javascript.
