I am glad you wrote. I am also an RN, and I am just filling out the paperwork to get registered with the nmc (I am here with my dh's job).
I initially went through an agency (OES) to get the paperwork started, but I am going to go directly to a nearby hospital and see if something can be worked out to speed things up ---I was told I MAY be able to be registered and working in 4 months. (there is a nurse shortage here, too)
We are going to be living close to where you will be, too! We are in London now, but we are moving to Leigh on Sea, essex, just north of Kent.
Let me know your progress, and ask me any questions, I find the NMC wait extremely frustrating as well!!
