Why I am not able to invite users to the free board

[Faizan Ahmed]

Hello, 

I only have 6 members on the Trello board. However, I am unable to add more members. As far as I know, I can invite 10 members. Could you please help me find a solution to this issue?

The 10 Collaborator limit for our free plan applies to the Workspace your board is in rather than the board itself. So while your board might have fewer than 10 members, if there are more collaborators in the Workspace or there are other boards in the workspace with more collaborators, this will cause you to see these notices.
