Do you know kgb.It is a kind of website that you can get by answering others questions.I passed the exam of kgb the day before yesterday.But I'm not an American so I can't be an agent of kgb.Is there other sites like kgb that pay you for answering questions? As far as I know, chacha is also a websites that pays people for answering ,but it's job is only available for Americans too.And there are a lot of "paid by answering" site seens to be scam.If you know any good sites like kgb,please tell me.Thank you.
