[RenoT]

Hey there, what if I invite someone onto one Trello board, and this person is not belong to this team, will he be accessible to other boards in this team as well, or just the board I invited her/him onto?

Hi, 

When you invite someone in a board , you must precise if you are adding 

- as admin 

- as normal (member)

- as observer

Regarding to this,  his permissions are variable.

Hey Ludo,

It depend on whether you are business class or not, if not, you are not able to do that, sounds like she/he will become member of the team if you invite her/him onto one of board in that team...

Indeed, advanced permissions are available only with business class account.
