This depends on whether you have purchased a number of seats for the application (for example, for a group of your colleagues), or just one seat for yourself.
If you have purchased a number of seats for the application for yourself and a group of colleagues, you can invite these colleagues to compare GlobeSmart Profiles. First, your colleagues should register for the site according to the instructions sent to you after your purchase. Once they have registered, you can then send them invitations and compare GlobeSmart Profiles.
If you have purchased one seat for yourself, you can invite colleagues or friends to compare GlobeSmart Profiles. However, before they will be able to access the site and create their profile, they will first have to purchase a seat for the application by going to http://www.aperianglobal.com/store/
