I've gone into the texturing sides of things, as this was a question asked even b4 o2 was released to the public. I might make it into website form when i get the chance.
I've also covered how to get the addon ingame and such. if you are learning to model my advice is to read brssebs tut.http://ofp.info/brsseb
Or read the tutorial o2 came with
Next version of my tutorial (which will be coming out later today, or tommorow) will contain how to model in o2.
anyway, you can get my tut from,http://www.ofpec.com/editors/tutorial_view.php?id=85
The updated version of my tut will be on the OFPHQ first. And OFPEC whenever they can get it uploaded...
