Yes it does, I don't know how it's performing lately but it was very difficult to log on too back in Feb/March which is why I took out the first class membership thing-which in my experience is worthwhile. If you are in Norway you might find it easier to get logged on since you are an extra one or two hours away from the US (in time zones) which is where the peak demand is.
There are other sites (avsim.com/simviation.com and others) where you can download planes/scenery etc but I have found FlightSim.com to be the easiest to use,and it's file library is bigger than anyone else's (I think).
When you start downloading make sure you are downloading real aircraft and not just repaints, they are installed in different ways.An aircraft must have 4 principle folders,Texture,Panels,Sound and Model, without these it won't fly. The 'How to install aircraft' tutorial goes into great detail and seems daunting at first,but with practice it's really straightforward.
Hope this helps.
you can't buy time but you can sell your soul and the closest thing to heaven is to rock'n'roll
