You can invite other members from your organisation into your workspace. There are two ways to do this.
1. Only administrators can invite other team members to join. Click on the 'Invite New Member' button.
2. Simply add email IDs of your team members, choose the role and they would receive an invite in their mail inboxes.
3. Make your workspace discoverable, so that others from your organisation see it when they sign up. It is important to select the discoverability option on.
When the next person from your team creates an account, he or she will be offered a choice to join your workspace.
By default, all invitations are for Editor role but can be switched to Reader role as well at the time of invitations. You can also change the roles from the Members Option.
