Back in 2006 I built a custom CMS for golf membership/community to manage tournament listings and registrations along with club news and social calendars. In 2008 I migrated that to Drupal 6 and continued to grow the site from there. Come 2010 I was raising flags about moving to Drupal 7. No. 2011, I recommend the move. No. 2012, 2013, 2014, 2015 ...no, no, no. 2016 they complain that the site is old and they want more "management" capability (they had tons a capability). The get sold by some wizbang company and the fancy dancy CMS. I have to hear how great it is bla bla bla. That is until they start to use it. Turns out, it's not a CMS by any stretch of the imagination. They need to know HTML and a page's content in a single blob field. And content can't be repurposed across the site. I now just sit back and laugh at their pain.
