I've posted them on my web site for perusal and comments. The URL for the backgrounds is: http://www.ron-oakes.us/?q=node/46, and for the page that holds the character sheets is: http://www.ron-oakes.us/dnd_characters/.
I've enabled comments for the background pages. They will allow anonymous comments, but will ask for your name and e-mail address. I am 99% sure that only the name will be posted, but feel free to use a fake address if you are paranoid. The comments will also require a catchpa so that robots don't attack and will be screened initially. I suspect that if you have an account at drupal.org you may be able to log in to my site using it (I don't think I've disabled that option) but I'm not sure what you'd be able to do.
