Continuous Open Recruitment (COR) - (Formally called COB)
"Open Recruitment begins after the conclusion of Sorority Membership Recruitment Week and continues throughout the academic year. Open Recruitment is recommended for anyone who chooses not to participate in Membership Recruitment Week or did not receive a bid during the week. It offers women the opportunity to participate in sorority life and join a sorority through an informal process. Membership recruitment activities might include pizza parties, bowling outings and TV nights. Participating sororities will contact you by phone, letter, or personal visit to invite you to attend their membership activities.
You can register for COR in 575 Patterson Office Tower or by

And for what it is worth, if you do consider COR, in my humble and completely unbiased opinion, all chapters at UK are great.
Best of luck with whatever you decide.
