I wish to add a person to my membership, but that membership does not expire for several months. How can I do that?

There are two things you can do. In either case you will need to contact the SFI Member Services HelpDesk for assistance. 1. You can add the person to your current membership without any cost. This means that your person will NOT receive any membership materials. 2. You can add the person to your membership and pay the difference between your current membership type (for example: single) and the new membership type (for example: family of two).
