I'm starting work on a Trello board ware I will direct participants of a game design project to. Many of these participants I will have never met before and I can't possibly know their intent.
I've already done all I can to protect the project itself, but I need some way to protect its Trello documentation and the other Trello accounts. My plan is to temporarily remove offending users, contact them about the offence if possible, and undo the damage that was caused as much as possible.
In most cases, I can replace damaged lists and cards from a backup board, but I need to know what was damaged. Is there any feature, or power-up available that could track when the description of a card is changed? Or better yet, undo a user's changes when I remove them from the board.
