Sometimes you want to understand not only what the outcome of a question you're asking is going to be, but how specific types of people are trading.
For a long time we've allowed administrators to capture additional information about people when they complete their profile pages, but now we give you the option of making some of those questions required during the registration process.
For example, a consulting firm we're working with is requiring people to enter a Department Code during registration. They can now cross-reference this information with trading information and gain new insights about the behavior of the community, e.g. People from one department think the chances are high an event will occur, where as people from another department don't agree.
