If the message analyzer 232 determines that two or more communication sessions share a common ground and that users associated with the two or more communication sessions are related, the message analyzer 232 may send, to the session merger tool 234, an indication that the two or more communication sessions share a common ground and that users associated with the two or more communication sessions are related. Based on the indication, the session merger tool 234 may determine to recommend merging the two or more communication sessions to generate a common communication session between the user 1, the user 2, and the user 3. The session merger tool 234 may determine a common communication channel for the common communication session. The common communication channel may be determined based on the communication channels for the two or more communication sessions, communication channels used for prior communication sessions between the users, and/or content of the two or more communication sessions.
