My Trello was recently set to view only because it turns out one of my old accounts with an employer I no longer work with hosts a board with more than ten members. I'd like to find a way to merge all three of my trello accounts into one and then look into the paid plan options from there. Any guidance on how to do this? The one with the boards I actually use is an inactive email address, so when Trello sends it a confirmation email when I try to log into that account, I'm stuck.
