Is anyone interested?! Just wait until Josh sees your later post, Trooperman. ;) Then you will know the true meaning of interest. Or obsession. Whatever.
It would be neat if you would be in Paul throughout his work to help out with little things. Do you plan to do so? I think it's important that you're happy with the final product, too. I can't speak for Paul, of course, but I bet he feels the same way.
I'd love to do some voice-over stuff, too. I doubt it'll happen, but it's something I've been interested in for much of my life, and I am a public speaker as well. :p
