Good luck, siglamb...to you and all of your sisters. When does recruitment start? And maybe I missed this, but have you decided (in your local chapter) what is going to be done?
IMHO, I say stay local. When you don't disband, maybe Panhell will see what a mistake they made by not keeping you informed. I don't want the new SSS chapter to be a failure, but I think you should stand your ground! Good luck!
