This is more of an outline of the standard than digging into the specifics in the detail some of us have seen, but it is a step forward.

Now that you are at the end, I'm Beginning!
Darn, My PEG TV station clients missed out on the DOM project group. But, they love the project and want me to upgrade their very static web site to the Open Media Project model. I know you are all working very hard on the installation profile, and that it is not ready. So, if I begin the project without the profile, is there some documentation somewhere that sets out what modules get installed at what stage, etc., along with known pitfalls, or umm, possible problems?
P.S. If you need a beta tester for the installation profile, I volunteer! (I can take it, believe me, I've already been through this a few times.) I am running Ubuntu 9.04, and have the most recent installation of LAMPP.
