Adding people to a board
We're going through some changes! Trello Teams are now Workspaces. Soon, all boards will be in a Workspace. You might see us mention Teams in a few places as we're going through these changes. Thanks for your patience!
To add members to a board, select "Invite" from the board menu. Search for a user by name or enter an email address to invite them to the board. Click their name to add them to the board. Depending on the board settings, you may need to be an admin to invite someone to the board.
You can add members to boards even if they are not already using Trello. Just enter the person's email address and click "Send invitation." The user's permission level will be considered " Virtual" until they join Trello, but you can still add the user to cards.
Add other Trello members or invite new users to your board and collaborate in style!
Adding someone as an admin
You can make someone an admin of a board after they've been added as a member.
Adding someone as an observer
Boards in Premium Workspaces can also have Observers in addition to normal members. Observers are board members that are able to view a board and the cards within the board, download card attachments, comment and vote on cards (if that is enabled for the board), and export the board.
Observers are not able to move or edit cards, upload card attachments, tick the box on a checklist item, and Observers can't change board settings. Observers are treated the same as normal members of the board from a billing perspective.
Inviting people by using a shareable link
You can also invite others to your boards by sharing a special link with them. Read more about that here.
Allow Workspace members to join
If you would like any of your Workspace members to be able to join the board and collaborate, you can select "Allow team members to join" from "More"->" Settings" in the board menu. When you select this option a checkmark will appear next to "Allow team members to join" and your Workspace members can add themselves to the board.
You can further control board permissions in the "Settings" option in the board menu (click "More" to expand the menu options). Under "Commenting permissions," you can select who is allowed to comment on the board: no one, just board members, board members and observers, all Workspace members (whether or not they're board members), or any Trello user.
Select who is allowed to comment on your board.
Using the "Invitations permissions" menu, you can select who's allowed to invite new members to your board. If "Admins" is selected, only board administrators can invite new members. If "All members" is selected, any board member can invite a new member to your board.
Troubleshooting board invitations
The newly invited person sees a banner that says "You'll need to create an account for Trello to join the board" even though they're logged into an account registered to that email.
To fix this problem, the admin of the board will need to remove the invited Virtual member's accounts from the board and invite them again using the same email address. That should link up with the right account now and grant the new member access to the board as expected!
