I'm attempting to get Trello incorporated into my company, but one of the issues we're running into is with vacation requests. Right now we have it all go through email, and I want it to go through Trello cards. The problem I'm running into is that we can't have other employees see other people's requests. So what I'm wondering is if there is a way to have a card become hidden to others when it is submitted, and only visible to the administration team. That way we can address it without others seeing the request. This is to avoid FMLA and other types of privacy issues.
