ITs not a matter of "trust" its a case of "common courteous", basically you haven't yet got permission so the decent thing is not to to do it, but also it protects yourself. If you do it without permission, and it turns out CFM disapproved, you could be held for it.

Considering CFM's history and reaction to past illegal activities as it is, I honestly don't think you'd get in trouble to be frank... But its better safe then sorry. Plus, its more professional and tactful for you as a "fan rep" as per say.

Now there is a form of proof no one should really have any criticism. But DO get a copy of that and take it with you when you go to the con as a "just in case" measure.
