My campus does bid matching by hand right after pref. (we only have about 90 or so girls to match to three sororities, so it's not too bad) Our rules state that only two advisors from each sorority are to attend, unless there is a national officer present.
My question is, is this something my campus came up with, or are there national NPC regulations about how many alum/advisors can be present and do bid matching ??
