How wonderful! Deciding to go through rush was one of the best decisions I've ever made. Try checking out the national websites of the GLO's on your campus; they'll give you lots of information on the group in general, as well as links to collegiate chapters' websites. If it's available, look at the sites of the chapters at your school, as well as any Greek Life pages your university has. That helped take the edge off of waiting for rush for me! Good luck with rush, even though you guys sound like you don't need it.
