I am building a customer community where I want to include a kind of Ideas group. Pretty much a rip-off of the most simple features from http://mystarbucksidea.force.com/ where users can post ideas / features, comment on ideas already posted and make a simple "hot or not" vote. Anyone who knows about of a Drupal module that does this trick out of the box? The closest I got so far is to use the Voting API and build custom code on top of that.
