I joined trello only 2 weeks back.
I invited a member, but see that he has all the administrative powers like creating new boards, inviting members etc.
How to restrict them? How to give specific permissions to them?
I am particularly concerned because if any invited member by mistake or by malicious intent upgrades to Business class, then I might be charged for it.
Request everyone to enlighten me on the subject. I intend only to subscribe to Trello Gold and not Business class. Please give me tips and tricks to follow.
