Professional/service fraternity recruitment

[Miriverite]

For those who are actively involved in a professional or service fraternity (ex. Delta Sigma Pi, Alpha Phi Omega, etc.)

How do you recruit? Since it is possible for a person to hold membership in both a social + a professional/service fraternity, how do you arrange events such that PNMs have the time to attend yours? How does pledging work for them, since if they choose to pledge two they would arguably have to go through TWO pledge periods, which is a bit harsh depending on the culture of GLO's at the school. What interesting events have you held that set you apart from the social GLO's?
