Systems and methods are disclosed in which merchants on an e-commerce platform may use a same computer application to start and/or join discussion groups with other merchants on the e-commerce platform. An existing discussion group may be recommended to a merchant based on data specific to that merchant. A notification of the recommendation may be transmitted to the user interface of the merchant's device, and if the merchant accepts the recommendation, then the discussion group may be added to the set of discussion groups the merchant follows. Alternatively, a recommended discussion group may be automatically added to the set of discussion groups the merchant follows.
