Abstract: Methods and systems are disclosed for joining community subgroups on a messaging platform. The methods and systems perform operations comprising: receiving, from a client device, account information associated with a user; searching, by a server, a list of communities to identify an individual community that corresponds to the account information; selecting a subgroup of a plurality of subgroups associated with the individual community in response to identifying the individual community; storing, by the server, the account information in association with the individual community; and adding the user to the subgroup to enable the client device of the user to access information of the selected subgroup that is exclusively available to members of the subgroup.
