I'm from IU, but my chapter expanded beyond our bed quota during my junior and senior years. We took a PC of 80something this year, and it is really a full-time job.
I can't talk about the selection part, obviously, as that's MSS
It takes time to remember everyone, and sometimes you still get girls confused. I had moments where I was like shit...I know you. I know you, I KNOW YOU WHY CAN'T I REMEMBER YOUR NAME?!?! You gradually meet them, we have 'Lion Links' so one active is assigned to one new member each week or two, that helps, and then you go out to dinner with other lion links and you gradually get to know them in small groups. It really is a challenge, but you do it. Comes in handy when you join new offices and have to learn names
