Question: I subscribed to a bone marrow registry a couple years ago, but now I relocated to another country. Should I register again? (both countries are in the EU)

I guess that if I'm compatible I will still be notified by the registry in the old country (or at least, my family will be notified)... and it'll only be a bit of an hassle to handle the donation, but it shouldn't be terribly urgent to resubscribe, am I right?
