Training is huge and key at all levels of the volunteer chain, including at the very basic level where people are out canvassing and have information. Obviously, limiting access as well, so people only have access to the information they need is important, and in addition to that, where people do have access, ensuring that there are protections in place.
We have our Liberalist user agreement, where anybody who has access to it is bound by it and has agreed to ensure to hold that information and to return it at the end of their use so that they actually don't maintain any of that information. They're reminded of those obligations from the very moment they begin to have any access to it.
