Yay! If you end up moving to the Sussex area, we'll have to meet up!
One evil note of foreboding, though - check up on all immigration matters before your husband accepts any positions! Immigration is expensive, takes time to plan, and is a total pain. If I were you, I'd go ahead and get the ball rolling on UK citizenship for yourself (which, under certain circumstances, may mean that your kids will be eligible as well, but not necessarily), and do homework on how to go about getting visas for your family and how much they'll cost.
But that's just the legal stuff. Good luck! I hope you're soon over here, spending your days writing and loving life!
