Hmm, what would the Nunsignal look like? A ruler smacking the back of a hand?

I was picturing a halo, but the ruler does make more sense.

The highlight was the incredibly cute study/reading room whose entrance is made to look like you're entering the wardrobe from Lewis' Narnia books (complete with a curtain of hanging fur stoles you have to push your way through).

That sounds delightful!

The Nunsignal (okay, email) was answered! Sr. E. said she would ask the other sisters to pray for Tim as well, and I suddenly pictured the lighting of the beacons in RotK.
