The user interface is great - it's intuitive, easy to use even for new users (which I am).
It has many useful features that can be configured in advance so you don't have an initial learning curve with your organization when setting up its first implementation of this software/website! Some people might find some things confusing at times but they are working hard behind closed doors fixing those issues as we speak right now!! So far my experience using TRAIL BLAZER NPM was really good because everything works flawlessly like clockwork without any glitches or problems whatsoever once installed AND IT'S FREE.
