Sharing links to cards, boards, comments and actions

You can easily obtain and share a link to a board, card, comment or action in Trello. If you are linking to a private item then the person you are sharing the link with must be a member of that board in order to open the link. Links to team visible items can be opened by members of your team but one will still have to be a member of the board to collaborate on the linked item. A link to a public item on a public board can be opened by anyone that has been given the link.

Linking to boards

To obtain a link for your Trello board, open the board's menu, then click "More", and copy the link to your board.
