2. The data transmitting apparatus according to claim 1 , wherein the storage unit further stores information indicating a correspondence between the plurality of users of the data transmitting apparatus and a group corresponding to at least one of the plurality of users.

3. The data transmitting apparatus according to claim 1 , wherein the display control unit displays the first registering screen or the second registering screen on a display unit.

4. A controlling method for a data transmitting apparatus that is shared by a plurality of users, comprising: storing a plurality of destination addresses in a storage unit, wherein an address book is comprised of at least a part of the plurality of destination addresses stored in the storage unit, and wherein the plurality of destination addresses include a destination address which is made public to a specific user, a destination address which is made public to a specific group including a plurality of users and a destination address which is made public to any user; transmitting image data to at least one destination address selected from the plurality of destination addresses stored in the storage unit; and generating, when receiving an instruction to register a new address from a user who has logged in to the data transmitting apparatus, (i) if the user belongs to at least one group, a first registering screen with which it is selectable to register the new address to be registered as the destination address which is made public to the user, as the destination address which is made public to the group to which the user belong, or as the destination address which is made public to the any user, and (ii) if the user does not belong to any group, a second registering screen with which it is selectable to register the new address to be registered as the destination address which is made public to the user or as the destination address which is made public to the any user.

5. A non-transitory computer readable storage medium which stores a program for causing a processor to execute a controlling method for a data transmitting apparatus that is shared by a plurality of users, the controlling method comprising: generating, when receiving an instruction to register a new address from a user who has logged in to the data transmitting apparatus, (i) if the user belongs to at least one group, a first registering screen with which it is selectable to register the new address to be registered as the destination address which is made public to the user, as the destination address which is made public to the group to which the user belong, or as the destination address which is made public to the any user, and (ii) if the user does not belong to any group, a second registering screen with which it is selectable to register the new address to be registered as the destination address which is made public to the user or as the destination address which is made public to the any user.
