Tony - From the people I'm speaking to today, and the response I'm seeing here on the forums, many people in the community are perceiving your email blast/news announcement as a fear-based marketing tactic. Which brings me to another point.
On the "Testimonials" page of the PowerDNN site, you've prominently included a quote that reads "You guys, are great! Without your support DNN sucks!" (Yes, someone else's words, not yours right?) So my question to you Tony - Do you agree with this statement, especially so much so that you have used it as a marketing tool (testimonial) on your site?
I think your answer, not to me, but to everyone in the community who participates with the DNN project - users, team members, consultants, designers, etc. - will have alot to say about your midset and the manner in which you handled the security issue.
