Establishing an ad-hoc group based on addresses in an e-mail

This invention describes a method for establishing an ad-hoc group based on addresses of users in a message (e.g., an e-mail) received or sent using a pre-selected communication method (e.g., an e-mail communication) by an electronic device. Any recipient or a sender of the e-mail message can use the e-mail addresses in the message in order to establish a permanent (stored in the device) or a temporary (used immediately in a context of another communication application) ad-hoc group. The user may select all or only a part of the people (other users) into the ad-hoc group. The group-data can have several types of addresses of users such as phone numbers, SIP addresses, wireless village IDs, etc. needed in conjunction with desired applications. Creating the ad-hoc group from the e-mail message can utilize information that already exists in the electronic device and, if needed, acquired additional information from a remote service.
