Catching up

OK I know my homework is overdue and it is too late for the contest, but I will not rest till I get caught up.

The cyrptogram reveals the sentance:
Can you keep a secret? The headquarters for the order of the phoenix is at no. 12 grimmauld place.

(of course now everyone knows where it is!)

Also my brief bio:

I am an adult witch who graduated from Hogwarts in her youth, but is attending again to gain an advanced degree in potions and medieval muggle studies. I was employed and the US Ministry of Magic in Potions research and development, but my assignement has run its course. I am now trying to use my magicical craft abilities to cater to the muggle population. Having studied how difficult it is for the muggles to do things like knit and sew without magic, I feel it my duty to help them out! I am married to a wonderful wizard named Rudolphus who is currently working on assignment at the Ministry in the UK to help restore the landscape destroyed during the past few years by He who must not be named and his groupies. I have a son, Grompton who attends Hogwarts pre-school. We are all active in dueling and I really enjoy knitting with my pal Molly.
