I would really like to help out to repay Bhikshu Dharmamitra from some of his tireless work. Unfortunately, I'm big on the techie, not so much on the design, and no experience with Adobe Indesign. If I find some free time to pick it up or if one of my friends is skilled & available enough that I can send them your way, I'll let you know. Sorry that I'm not much help; just felt kinda bad that there weren't more replies. I think most people who've read this and would otherwise want to volunteer are in the same boat as me.
Bhikshu Dharmamitra's translations are very helpful--he's doing a great service to the Dharma by promoting the teachings in this way. I do hope he gets the help he needs to continue producing these important texts.
