I'm not quite sure why you're posting in Fraternity Recruitment if you're in a sorority, but what the heck.
First off - "no frills" or any of the panhellenic rush rules like that shouldn't apply when it comes to COB. That's only to give chapters an equal playing field in formal rush.
That being said - don't make the mistake of trying to make COB events the same as formal rush events. Keep it CASUAL and the emphasis on conversation and getting to know the rushees. You can have a theme, or not have a theme. You can invite the rushees to attend campus events with you. The main thing to look for is women who want to be in YOUR sorority - not just A sorority.
Good luck!
