Backdrop Port of Fivestar

This is complete. Fivestar for Backdrop CMS.

I've had discussions with some Drupal 7 users, who aren't aware of Backdrop. So, here's my understanding. Two years into the Drupal 8 project the core team decided to move to Symfony and also to make other large-scale changes to Drupal core, primarily to move from procedural to object-oriented code. Several members of the Drupal core team thought that was a bad idea, and forked Drupal to make Backdrop CMS. So, Backdrop is a version of Drupal which is ahead of Drupal 7 by a couple of years, but before the Symfony/object-oriented work began for the rest of Drupal 8. Anyone who knows Drupal 7 well should find Backdrop very familiar.

If anyone is interested in moving to Backdrop rather than the much heavier move to Drupal 8, but they need other Drupal 7 modules migrating too, please contact me.
