Upcoming Rush (Delta Sigma Theta)… ?

The Alumnae chapter of Delta Sigma Theta in ATL is holding rush in a week… they have not had held a rush in 6 years. I know there will be over 1500+ women pursing membership. I am wondering is there a cap on how may ladies they can choose and how do I ensure that I get notice? I have been attending events so I know several ladies in the chapter. I am just concern because they are expecting some many ladies to apply for membership.
