I love that this is open source, so we can really see what they are doing with their software (and not just take it for face value). The WG-Admin interface does need some work to make more intuitive but as of now it's pretty good! We use this product internally at my current job in order to manage our content library database/site structure. It has been very helpful because you have complete control over your site - no one else gets access unless given permission by an admin user or if there is something wrong with permissions from another system.
