It would seem that many youngsters want to learn. Yet their profile says nothing very much!
Take the Heading "Location". Many give their location as something frivolous, "Among the clouds", or even sillier such as "Away with the fairies."
Location is important. It gives an indication of country, of language, of culture. An indication of English being first or second language. Location should be just town and country; not postal address.
And, if you don't wish anyone to know your location, leave it blank!
