Hi! I was social chair last semester and the one pointer that I can give you is determine a fair and equal way to appoint sober sisters. My chapter ran into the problems of getting people to volunteer. And if they didn't volunteer, they were appointed--and usually the sister would say "well, I can't go now" or something like that. You can imagine the problems we encountered with that. Anyway, hopefully people will suggest ideas for this topic to help you out. Best of luck to you!
