Mcgonagall cleared her throat. "We want you all to meet up here at least once a week till Halloween to discuss your books, trade them or just have someone else to talk to about the process. May I suggest Friday evenings at 1900? We are happy for you to tell your friends you are participating in Potions mastery classes with Professor Slughorn at those times. Of course, being a registered animagus myself I invite you to ask me anything you like, I will be here next week at this time and then again the week before you need to make your choice."
