I haven't brought up this subject in a while; I think I should again. Everyone, please, fill in you profile, at least telling us approximately where you are.
If someone is flying into, say, Frankfurt, and asking for help using the trains to travel on, it sometimes helps if you know if they are coming from N. America, and will probably be getting in late in the morning, or if they are coming from other places in Europe and might be getting in earlier in the morning, or later in the day.
Or someone might be asking a question about immigration. The answer is different if you are from Schengen, or another part of Europe, or from the US.
So help out those who are trying to help you out. Tell us at least where you are from.
