It's going to be a bit of a mirror of what I said before, but not entirely.

And I probably will end up doing this repeatedly saying like, here's how it used to be.

And here's how it is today.

And that was something that obviously it's almost hard to conceive of how the organization could do what it does today, resident anyway, and our individual organizations without a registry itself.

And so the registry itself, As a part of that, the tools that Resonant has needed and providers, whether it's a provider, a rating company, a rater themselves in the field, the tools that we need to stay on top of all the complexities that Matthew pointed out, the changes in the way that builders build, and all of those things have required... continual evolution and continually high levels of sophistication in the tools.

So with this complexity, is there the opportunity for any one of you to speak towards how to get homeowners to really understand the value of the HERS score?
