Contacting Rush Chairmen and the IFC

[Amicus]

I was viewing the web sites of Interfraternity Councils and fraternity chapters at various colleges and universities. At a number of larger schools, men interested in rushing are asked to register with the IFC at their school. I also noticed that a number of fraternity chapters ask potential rushees to contact their rush chairmen.

Here's my question: at schools with 10, 20 or more chapters, is registering with IFC enough effort? Do men actually contact all the fraternities on campus, even if there are more than a score of chapters. In particular, I am thinking about young men who are interested in fraternity life who might not know much about fraternities as a whole or individual chapters in particular.

Just curious...
