Cannot remove guest accounts that are the creator of a board

[josef_bilek]

Hello, 

In our workspace we have two old guest accounts that we cannot remove because they were administrators and creators of boards. These users (guests) have left the company and we need your help to remove them.

Is it possible?

Our Trello account is Free level, we´ve got some members + many guests.

Yes, it is possible to remove the old guest accounts from the Workspace. By default, when you select the option to remove someone from the Workspace, the checkbox to remove the member from all boards within the Workspace will be checked. However, you can uncheck this box so they remain a board member on those boards – this will convert them into a board guest. If they are a board member on more than one board, they will be considered a multi-board guest and are billed at the same rate as a normal Workspace member. Alternatively, you can deactivate the users, which will remove their access from the Workspace and the boards within the Workspace, but you will still be able to see the cards to which the user belonged.

I cant seem to find a button/selection to remove one of these guest users? Which is an administrator/owner of a couple of boards the user created.
