Thanks for your answer. That would be an idea, but it's still an additional checkbox and we like to keep it simple, because asking thousands of users just to use 10 or 15 logos does not really worth it.

But I agree that theoretically T&C allow us to do more than using logos on our own website, I'll try to find a way to add a restriction on what we can do without explicit consent.

Thanks! (my nickname is simply 'damien' in my pro email address if you want to send me directly the mentioned email)
