Hi all! We'll (DH, 9yo DD and I) be joining you in January!
This is our second trip over the Atlantic. We moved to Sofia, BG, in August 2007 and repatriated in August 2009. Hopefully this time will be a little easier since I know the language (nuances to be learned shortly

)
DH is already there on a part-time basis, four weeks there and two weeks here. Partly because we want to ease our way over (we moved to BG only three months after the initial decision, avoid that if you can), and partly because we have two cats and a dog so we're in the PETS waiting period. His office is located on Knightsbridge, and he has decided he really likes Richmond so we're concentrating our house/flat/townhouse hunt there.
We're also home educating here in the US, but we may change that when we get there. Lots of details to look into.
Hope to learn from and help out other Yanks heading to London!
