An apparatus, method, and computer program product are described that determine a subset of users from a predefined distribution list based on a common characteristic of members of the subset. A common characteristic may be the fact that members of the subset have been determined to be proximate the source user's device. The source user may communicate (e.g., share content) with members of the identified subset through selection of the distribution list, while non-members of the subset would be excluded from the communication.
