"I would overhear sisters saying completely crazy things about J-Board (i.e you can't get called to j-board if you never show up to anything because, if you're not there, you can not be given the letter)."
yeah, that is bogus..... but I do like the way you took it upon yourselves to make it educational.
I would suggest this about calendar planning - Have all committee heads give their dates to the Vice Archon. The Archon, VA & Advisors should make a preliminary calendar first, and then the exec board will have their 2 cents. If you get the whole chapter involved @ once, it will take hours & trust me that happened in the past.
Retreat is also a great time to get new ideas from your new members that went through recruitment.
