We have a large team within our organisation that use Trello for our team project management, the board was set up by one employee and they are currently the only admin. This employee is currently off sick, with uncertainty on how long they will be off, and we urgently need to add new members to the board but as none of us have admin status we can't. We are looking for help to try and make more users admins so we can continue to use the current membership that has been set up uniquely for us. We don't want to have to make a new Workspace, as stated we are happy with the current membership, and don't wish to migrate everything.
