If you wish to save a contact for later you need to make a search, first of all. Once you get the search result page, you have to decide whether you're interested in saving a member's profile for later review or not. If you're interested, you need to press the 'Save to Contact List for Later' button. When you go to your Contact List page, you'll find the new profiles to look up later. If you wish to review the profiles before adding them to your Contact List, you need to click the 'View Profile' button. The system allows you to write to those members before adding them to your Contact List by clicking the 'Write to this member' button at the bottom of the profile.
