thats as far as national sororities go... depending on rules and whether you own your house....
my sorority owns our house- and always has- so the same rules really apply- we don't go parading around about having beer in the house- but there usually is- and we hold open parties and mixers there regularly...
as far as national fraternities- etc go- i'm not really sure how things operate- i would say as alumni and a board member- you guys have quite a bit of say of what goes on- but i really wouldn't have too much advise.. sorry
