Thanks all for the great comments and feedback.

Alex A: If it's concerning a specific product, it's usually best to go directly to the developer. I've heard varying reports on dealing with the MU guys but for me, probably because I'm a developer, I get timely responses.

Jason: I'm not sure what you mean by registration requests. I don't have any sort of on-line activation and a license is generated immediately when a bundle is purchased so there's no separate request in that sense. In any case, I have no way to gauge how many people are using/have registered the product beyond those asking for help. Is that what you are asking?
