The easy-to use interface is great! It makes it really quick & simple when looking up employees in our system without having access or needing an IT person around - which saves time as well so that we are more productive overall (as opposed than being stuck waiting).
I wish there were some sort of integration into LinkedIn because this would make things even easier but unfortunately not possible right now due to licensing issues? We've been using Agile 5 since early last year/year end 2015 mainly through internal training courses where people come together within departments / teams etc..
