Stop the scenario that leads members to resent the chapter for controlling their lives and time for weeks on end. Drop the mandatory policy for all members. Let the people who want to be in Greek Sing be in it and let the rest give moral support and be in the crowd to cheer on the chapter. Plus those people who want to do it and truly enjoy it will give their all to do the chapter proud and put on a great show. And they, at least, will have a damn good time doing it.
Every chapter talks about the importance of community service.
Yet on Philanthropy Day there are chapters that don't have a single person show up. We can be rightfully proud of the service done all year and during Greek Week. But especially during Greek Week the community and campus service reflects well on the whole Greek community- every single chapter. Similar to above. Let's up the participation fee by one dollar a person.
