Discourse is a modern, open-source forum package with a lot of benefits over phpBB:
- A live preview when composing a post.
- Topics and forums use “infinite scrolling” instead of getting broken up into pages.
- Easier to use on phones and tablets.
- You can “like” a post.
- Statistics, badges, and trust levels.
- Better spam protection and flagging.
- HTTPS: the whole forum is now encrypted.
You can read a lot more about Discourse on its “About” page. If you have any suggestions or feedback on the change, you can reply to this post or make your own topic in the “About the Pololu Forum” category.
