Translation of Orthopädie

For example, if I am working very early in the morning, let's say 06.00 (that would be 09.00 your time), I don't notice it much. But 9 hours later, the system slows down, because people in Europe get online.
I have sent you my e-mail address. If you want to write me there, I could view the messages immediately. It would be easier than on the Vocabulix forum, as I'm not online often enough.
Since when have you been learning Spanish? My children are not on Vocabulix, they are too small for it. We have no time for the normal day activities, and we are always on the move with the children.
