Anyone have any experience with Backdrop CMS? Working with CiviCRM, WordPress has its limitations for more complex sites, and the Drupal 6/7/8 upgrade path is a thing of nightmares. Backdrop CMS (a fork of Drupal 7) seems to be taking all the things I liked from Drupal, but forking it to avoid all the things that are awful. I'm two days into Backdrop and kind of excited so far... the only downside being the level of documentation you'd expect from a newer project. Anyone have any experience working with Backdrop CMS or following it for longer than a week?
