I'm a bigtime geek/writer, and the natural outcome of this combination is Harry Potter and the Natural 20, my D&D/Harry Potter fanfic.

The rules are as follows: Milo functions entirely on D&D 3.5 rules, most of which can be referenced on www.d20srd.org. I'll be keeping as close as I can to the actual ruleset (any mistakes are unintentional and I'll fix them if pointed out, not deliberately ignored for the purposes of the plot).

I'm also working on my own RPG, which can be found for free here (shameless plug): www.semiautomagic.org. Harry Potter and the Natural 20 will update every Thursday, ideally, until it's done.

Milo's character sheet at the start of the story can be found here: http://www.myth-weavers.com/sheetview.php?sheetid=398543,
Milo's character sheet as of the end of Chapter 2 can be found here: http://www.myth-weavers.com/sheetview.php?sheetid=435897
And Chapter 11: http://www.myth-weavers.com/sheetview.php?sheetid=421496

Unfortunately, the website I use for character sheets (which is fantastic, by the way) doesn't let you copy the sheets. That means that every time I want to update it, I have to redo it from scratch if I don't want to overwrite the earlier ones. The result of this is that the sheets won't always be up-to-date.
