Re: Hi there,

Dear Sir,

You are welcome to respond to me in French.

I am sorry to have to say that your letter was incomprehensible at one
point. namely where you said :

". What's the best way to participate, with a demo, a presentation?"

I would like to know where you got my name and I would not mind you sending
me information.  If I get a chance I will look at your page later today.

Thank you for your note,
Vaughn Ohlman

PS When writing business to business one does not typically begin ones
letter with "hi there".
