This is something I see everyday. Folks put questions in the app reviews on the marketplace for a particular application and then get mad when they don't get a response from the developer. They don't realize its physically impossible for a developer to respond to a question in the app reviews as we have no ability to figure out who you are and marketplace gives us no way to respond. Most all the developers I have dealt with on the marketplace are really good about responding to emails and questions. So if you have a question drop the developer a note, the developers email and website address should be in the "about the developer" section on the app listing on the marketplace. And you can click right there to send them an email. Good applications come from good communication between developers and those who use the applications.
