An app forum for rails 3

I'm looking for a forum app for rai开发者_如何学运维ls 3. All the forums is for rails2.

Any suggestions?

Thanks

Forem is a Rails 3.1 engine and it looks pretty legit.

I saw that rboard is rails3 based, I haven't tried it though.

For a more modern alternative, you could try Discourse.
