I have an online form where a user would usually submit a specific location in a field, e.g. Moscow, Berlin, New York, Paris. But sometimes there is no specific city location, for instance for a seminar that takes place "online" or a web screening.
I want to enable the users to enter the "worldwide" case. What are typical phrases in English for that to catch? Planet, www, online, internet, worldwide, anywhere. Can you imagine up more suitable candidates? Are you aware of any existing English geo-databases with entries for the worldwide location case?
