No problem! DPL stands for dedicated proof listener, and if a project has a DPL, it means that that person will listen to each section of the whole project. When I get home, I can send you a link that will explain what to do while PLing, what kinds of things you're listening for, etc. I could find it now, but I'm on my mobile, and it's harder to navigate on it. Then you can decide whether or not you're comfortable PLing my sections.
Also when I get home, if we're all set, and I think we are, I can go ahead and launch this. Sound ok?
