Please, can anybody answer me 2 questions:
1. is limit to request country code by web service CountryCode?lat=lat&lng=lng?
2. what is difference between ws.geonames.org and api.geonames.org?
When i read api documentaion, i see example url:http://api.geonames.org/countryCode?lat=lat&lng=lng&username=demo
But when i download GeonamesDotOrgDotNet project for .Net 3.5, i saw that project use http://ws.geonames.org/countryCode?lat=47.03&lng=10.2 link in code
