When you post a link in Discourse with any character in front or behind that link, Discourse automatically uses the blog, topic or link’s title in place of the link in the cooked post. So for instance the text you see are just links:
- Discourse 2.6 released!
https://blog.discourse.org/2020/11/discourse-2-6-released/ - Put images directly in notification e-mails
https://meta.discourse.org/t/put-images-directly-in-notification-e-mails/139965
Then if you post them on separate lines with a space before each link, select them all and click the bullet format icon in your composer, you’d have them in lists.
