sigep

Hello I am a freshmen and i am really curious but why wasn't sigma phi epsilon out there during discover feast. I see that they are here on campus since they are on the list of fraternity here on this website. the reason i ask is because i would like to rush Sigep but idk why they weren't there during discover feast. Are they on probation? sorry if this question is annoying but i really like to be apart of sigep especially since my model was part of sigma phi epsilon Theodore Suess.Thanks for reading
