I took a few days to think this over, and I'm definitely interested in offering some help for this. I'd probably be most interested in writing about combat and how to attack certain enemies, and I would be VERY VERY interested in writing about how to handle crazy battles, such as more than one dragon, multiple kinds of enemies, etc. My posts in the "your WOW moments" thread contain a lot of this.
I've also decided on a lot of things I feel could be improved in Skyrim, and I could really go on about what I think is wrong, how it could be improved, etc, such as how and why dragon combat should be improved. That sort of thing.
