If I have a standard or above account and share a board with someone on a free account - will they be able to contribute to that board, such as add or move cards?
If a card has paid-for only features, such as a custom field, will those users be able to update those custom fields, or will they be locked due to their account level?
Is there granular permissions, so someone can add, edit or move cards but not create or delete lists?
