Hi @Megatank58 ,

Welcome to the community!

Please read carefully and follow the steps below!

Changing the visibility of a board to public, private, or team

Board admin can set the board's visibility by clicking the board's current visibility setting, to the right of the board's name, and selecting a new visibility setting.

On free and Business Class team boards, admin can set the visibility to private, team-visible, or public. Enterprise team boards have an Organization Visible option.

Private

When a board is private, only those users added as members to the board can view or edit it. Private boards which are a part of teams are visible only to added members, unless they are part of a Business Class team or Trello Enterprise—then, they are also visible to team admin and Enterprise admin.

Team

A board must be added to a team to enable this visibility level. A team visible board will be visible and editable by members of the team by default. Team board admins can restrict members from joining and editing the team board in the board's settings. 

Organization Visible

The Organization Visible Boards option is a Trello Enterprise feature that introduces a new level of board visibility for Enterprise users. When a board is created or set as ‘Organization Visible,’ it means that anyone who is a member of the Enterprise (on any team that is owned by the Enterprise) can view the board, regardless of the team the board is in.

Public

A public board is visible to anyone on the internet and will show up in search engines like Google. Only those users added as members to the board can edit, but any person with the link can view, even if they don't have a Trello account.

Setting a board to public allows all members of Trello to view your board and optionally vote or comment. You can turn other features (like comments and voting) on and off for public members via the 'Settings' menu.

Note: Boards within teams that subscribe to  Business Class will see additional privileges for the team's admins, such as the ability to see and edit all boards in a team.

Changing permissions on a board

Set the visibility and permissions of features by going to the Menu on the right side of the board, then clicking 'More' then 'Settings'. Permissions and options will vary per user.

Board admins have a different set of permissions on a board. Only a board admin can remove users and change the commenting permissions, for instance.

Types of Trello Users

When it comes to permissions on a board, there are different types of Trello users:

• Invited Members - An invited user is someone who has been invited to a board but who hasn't yet confirmed their account. Their user icon will appear to be grayed out in the Members area of the board.
• Board Members  - A normal member is simply a member of a board. 
• Observers  - An observer is a member with read-only access to a board. (Observers are only available to teams with Trello Business Class).
• Team Members - You can make a board belong to a team, so a team member is a user who belongs to the same team as the board.
• Guest - A normal member on the board. The user is however not a member of the team that the boards belongs to.
• Board Admin - A board admin is a member of the board who can do anything on the board. Board admins are marked by the blue and white chevron in the bottom right corner of their avatar.

Commenting permissions

You can change who is allowed to comment on the cards on a board:

• Disabled - no one is allowed to comment.
• Members - Allow admins and normal members to comment. This is the default setting.
• Members and Observers - Allow admins, normal members, and observers to comment.
• Team members - Allow admins, normal members, observers, and team members to comment.
• Public members - Allow any Trello member to comment. This option is only available for public boards.

Invitations permissions

You can change who is allowed to add members to a board:

• Admins - Allow only board admins to add and invite others.
• All Members - Allow members and board admins to add and invite others. This is the default setting.

NOTE: If a board belongs to a team, you can enable the setting " Allow Team Members to Join," which will allow any team member to join the board without being invited. To enable this, the board must belong to a team and the board cannot be private.
