I am thinking about creating a team project, but unfortunately my team members can't visit me often as they are far away from my home. So I'll be needing a secure, free, team management software, and I came across Trello. Adding members to Trello seems too easy, that I really think I have to ask about it here. I was reading this: http://help.trello.com/article/717-adding-people-to-a-board and realized that just choosing someone by name is enough to add them into our board.
Because there is no "invitation" system, where a Trello board admin sends a message inviting a participant and the participant having to accept the invitation to join the board, people can anonymously add others into a Trello board and literally "spam" them with messages.
Isn't it insecure to be able to add anyone without their permission?
Best Answer
When you add someone to a board they have to accept before seeing your cards. They will receive a notification that you have invited them, and you will receive a notification when they have accepted. Those invitations should also be in your board's history.
You can change the settings of a board to only allow team admins to add members: Show menu > Settings > Invitations Permissions
Trello Business Class has more finely-tuned options for member access; it might be more suited to your needs.
I hope this helps!
