Don't change any actor/actress his/her name into another one, while he or she is already credited for a show. It will mess up our system and show. I've spotted someone doing this already, but this is not meant for that.
You can edit their name if there's a small error in or not credited yet for any specific show, but do not change an actor into a complete different person, once it has been credited already!
Once we have a duplicate of an actor you could inform us and we will fix it :)
