An insider's guide to the sorority recruitment process. For many girls at Boston University, the envelope they receive on the fifth day of sorority recruitment is much more than simply an envelope.

Last week, more than 500 female BU students took part in the spring sorority recruitment at the Marriot Copley hotel, said College of Communication sophomore and Alpha Phi member Torre Price. Despite the stereotypes surrounding sorority life, 11 percent of the BU population belongs to a Greek organization, according to BU’s website.
