I manage a running club. On the advice of a pal, we used Drupal to develop the club website. This went well enough when my pal managed the Drupal site, but when he got too busy, the thing became a nightmare. Our club management (a handful of runners) ended up spending an inordinate amount of time and money addressing Drupal updates and hacks and technical stuff that was far removed from doing what we loved and were good with (managing a running club.)
If you register a domain with Bluehost when signing up for a hosting account, there is a domain fee that is non-refundable. This not only covers our costs, but ensures that you won't lose your domain name. Regardless of the status of your hosting service, you'll be free to manage it, transfer it after any required lock periods, or simply point it elsewhere at your convenience. You retain ownership of your domain until the end of its registration period unless you elect to extend it.
