Hi, a member of my team is leaving the business and he set up our entire Trello account using his email address. Myself (manager) and other team members are admins on boards but not able to make certain changes as the original team member (Barry) set it all up. I am concerned that when he leaves and his email account is closed by the business, we will have a major issue with Trello and access, so I need to understand how we change him from being the main admin/set up account. We are on the free version and I have tried many ways to do this but not been successful. Yours support would be appreciated. Thanks
