TJ,
You also put yourself in a tough situation by not forcing customer
feedback into a registered web page that standardizes the customer
feedback collection process. You should not take ANY product changes
through this message board forum -- it sends the wrong message to
customers. You should listen, and offer advice, but that's it. All
product changes should happen as a result of looking at the larger
customer audience who uses your feedback form. I would imagine a
larger percentage of your customer audience sees your web site but
never sees this message board, for example. How do you know? You
never will know until your force people to register with your web
site.
Make sure to make every effort to tie those registrations back to
the products these customers actually own. Keep in mind you are
working at two levels -- customer acquisition and customer
retention. I'll let you research the difference and what that means
to you.
Do not make the mistake of assuming feedback on this message board
is representative of what is best for all of your customers -- both
potential customers, and also existing customers.
That's all for now... back to trading!
Regards,
Brian
