Papers, templates and too many authors?

A couple of teams have asked that since the template only has provision for two authors, how should they format their paper to deal with 3–5 team members. Have a look at this student paper from last year. The text box was reduced to having just one cell, and then a common information such as the University and email domain was grouped. The one change we should have suggested the team make was to include a little bit more information about the University (such as its address and country).
