With all due respect skyman, the international language of aviation is English - albeit with some operators (air france, ahem) deciding to speak their mother tongue within their own airspace.
Although you may not think so, the ability of a professional training school to have their website (these days, the primary marketing means after word of mouth) online using bad grammar/spelling really does discourage me from considering their school as somewhere to spend a very substantial amount of money.
Also, if I have that thought just through perusing their website, what thoughts go through the minds of the airlines in an interview situation if they have happened to view the website....
Perhaps that's just me then..........
