Playing with an opponent via email and we’d like to switch sides. How do we do that. I tried but it only allows a choice of observer or solitaire.
You can’t force someone else out of a side–it’s locked by their personal module password. So first you take observer status (the state of not being in a player side at all) and save. Send this file, the opponent will now be able to switch out of their side into the one you just vacated, they save and send back to you, their old side is now available for you to leave observer status and take it.
