Hi,

Well, you saw already form the first reply that there might be people that dislike it, for sure, and I include myself there... but fact is, you're telling that the client can choose to participate or not. For me I don't like the idea of having a program sending out stuff, but well, who knows how many does it without I knowing it.

But in general terms, you can approach it in two ways, one gather statistics from usage, and another, having a feedback dialog or usage survey via e-mail, web, whatever, for sure the accuracy of the latter options is less.

Regards,
