It's been awhile since I have been on here
Let me offer some suggestions for your chapter. I was EVP of my chapter a couple of years ago, and I know how disrespectful talking, and note passing can be. What we did to combat those types of problems is by stating certain things are not allowed in the formal meetings (cell phones, talking w/out permisson, and note passing etc.). We normally made a general announcement during meeting about "please be considerate of Sigma Kappa ritual and cut out all the unnessary chit chatting, note passing, or whatever is going on."
Normally we had it set in our Code of Conduct what is allowed and not allowed in formal meeting If it became a problem with the same person then Standards Council can call them to standards. Just remind the ladies that it's ritual and that will get their attention. If it's not set in your CofC then you should make an admendment to your CofC and set guidelines for your your chapter during formal meeting.
