Dear Santiago,

In my opinion, you are not dealing with a foreign teacher, but with a Chinese recruiter.
The same Tony has just posted only a sentence about his job search under the name Bob, on www.eslteachersboard.com ( Resumes ). Bob has the same e-mail address like Tony.
Beware of Jeff Lee from Beijing Wellgo, who has sent e-mails to several teachers asking for the e-mail addresses of " good schools " ! ( " Short survey about schools " ). Jeff`s English is not always bad.
This is a common practice in China.
