A hub is a way to group contacts who you want to message easily or who may want to frequently message or share files and/or photos with one another. Hub admins are allowed to send messages, create events, and upload files within their hubs. Hub contacts will receive the messages, see events on the calendar, and have access to the files. Depending on the Hub settings, the Hub contacts may also be able to create messages and events and upload files.
Contacts in a Givebacks site can be assigned to as many Hubs as you want. Contacts can go to Communications > Join Hubs to choose hubs to join. Admins may also add contacts to hubs.
