Thank you very much for your message, and, yes, I would be interested in speaking at the conference you mentioned, is it right that it will take place in Paris? I understand from your message that you want me to talk about the results of marketing strategies, but would it be possible to get some further information about the kind of presentation that you require? Next week I will be on vacation in Miami, so it'd be great if you could return this call sometime this week.
