Groups can have up to 300 members. Only the group’s owner can request to increase the group’s member limit.
If you would like your group to be larger than 300 members, you can email a request to firstname.lastname@example.org. In your request, be sure to include:
- The account that you registered with and are using in 2or3.
- The group’s name.
- Why you want to increase the group’s member limit.
- And the new member limit you would like to have.
While it is possible to have large groups within 2or3, please keep in mind the purpose of having a group, which is to build community. Also remember that the group messages are reply-all, which means that whenever a member replies to the group, everyone in the group will get a notification.
