The most useful thing about phpnuke for me was that it allowed us to easily create new website pages, posts, galleries etc with very little effort. It also made updating them easy as well. I disliked having to make changes in multiple places if something wasn't working correctly or looking right (i.e. logo). If you are going to use this software then i would suggest hiring someone who knows how to customize your templates better than we did because there were some things which could have been improved upon by our designer. We used php nuke for several years before switching over completely to wordpress so we had no problems using it anymore.
