Thank you David. I really appreciate the level of collaborative support that I am receiving on this page. I plan to hold the session in October, as a present for my daughter's birthday. My birthday gift wil be her first RPG experience, with her best friends, in their beloved HP world. That's my plan.
I was an avid RPG player and master, back in old-school times. So my GM skills are rock solid - if we play the old school! But I realize that I must introduce them to RPGs in the way that they are played today. So I must re-start from scratch, and learn such a different gameplay (PBTA). Hope I find time in the coming weeks. I appreciate your availability and will contact you if needed.
Even if I don't contact you, I will take the time to 'report' about the session, if I manage to do it. :-)
