Nanners is definitely right. Recruitment isn't about the activity- it's about the people. I Heart Recruitment is an awesome resource! It talks alot about communicating to PNM's.

I joined my chapter because the women were interested in getting to know me and not just recruit me. Ironically, I was set on NOT JOINING at first, but they still continued to get to know me. I also ended up having a lot of my classes with the women in the chapter; so, we ended up studying together or being in other groups on campus together. As I got to know the girls, I got to know the sorority itself, and as time went on, I was able to see how wonderful the chapter was.

So, for activities, make sure it's something light that will enable the PNM's to get to know your chapter. I'd try to steer clear of movies and save those for a sisterhood type of event. I go to a service school; so, small service projects usually help to draw some people in.

Reading I Heart Recruitment is an awesome start. Also, check your sorority's website and look for any kind of training power points or things of the sort. They might be a little lengthy, but they're full of great information. Good luck!
