I joined expat.com on 22 July 2013.
There is much to see and do in Moscow. I very much enjoyed our tour there. If you get a chance to visit you should take the time to go to the parks they have (Gorky, Sokolniki). That is just a couple. They are very nice, especially in the summer.
The winters are long and dark. So if you are not use to that it would take some adjusting.
