Take the functional training required in becoming a master user of Powerproject (by Elecosoft), this online course will set you up to learn everything you need from the basics to an advanced navigator; traversing across each of the standard functional areas that allow users of the software to demonstrate their superior planning skills.
This also serves as a great refresh course for advanced users that want to re-visit some of the functionality lost in the halls of time, or learn some of the newer features not yet explored. After all habit is not necessarily the quickest way!
