I love fests! Of course, I'm a reader only. :) I can never keep up while they're being posted, but they provide reading material for months. I can only imagine the travails of the poor authors, but congrats on getting it done.

Re: Dark Mark - this confused me, because I swear I remember Snape (in Goblet of Fire) showing his Mark to Fudge (I think?) and saying that every Death Eater had got one from Voldemort. And how would he call them without one anyway? So I don't believe Draco ever was one, officially. At least not how Snape defines it. Of course, I don't believe his mother ever was one either.
