Reunion 9 for Mac can store contact information for people in your family files. Mailing addresses, phone numbers, email addresses, and web addresses can be stored for individuals and families. Contact lists can be generated and the information can be included in reports such as a family group sheet. You can even copy the information into and out of Reunion for use in other software.
I demonstrate all this and more in this video from the MacGenealogist Archives, Storing and Using Mailing Addresses in the Reunion for Macintosh Genealogy Software.
