Hey --- here's the SAME letter I received, from the email addy Huseyin Avni Sozen High School (with a link to the alleged Headmaster - Mehmet Keskin) BUT addressed to Dear Applicant:

I ALSO did some research on the school & honestly thought they were legit until I saw this thread (see the actual school web site & Wikipedia article on same, including translations for those of us who don't speak Turkish). After reading this, to include how to get the VISA, I have a call into the Turk Embassy here in DC & will advise of same on this site. I'm also curious what salary they offered the individual who began this thread ! My offer was MUCH higher than most positions I see advertised there.....GO FIGURE :-( How sad in this economy......or maybe thats exactly the reason for asking for 300 EUROS !
