From the developer:
4getMeNot is an electronic agenda to store email/web addresses, phone-numbers, and text data (postal-addresses, personal/confidential data, etc.). It dials phone/mobile-numbers and launches your emailer/browser. In addition, this program can import relevant data from Address Book, Eudora, vCards, and ldif/csv formats (i.e. Thunderbird etc.), and export data in vCard and ldif/csv formats.
You may want to check out more Mac applications, such as CST2Manage, Alchemy- or Project Hedgehog, which might be similar to 4getMeNot.
