We are registering school teams for a competition. We'd like to be able to either change the word "Guests" to "Teams", or have another option other than "Guests". Also, we'd like to make the field mandatory -- we had schools register, but they didn't see "Guests" all the way at the bottom, even with highlighted reminders, so they didn't register their teams. If it could be made to be a required field, they wouldn't miss what is at the bottom of the page.
