I added petition links to the ANHR Change List and RotJ Wishlist, which actually get a surprising number of people stumbling across them from all over the internet.
I don't want a whole thread just for my blog, so if you put a link on your blog, you could use this thread.
I added a link on the update of my page (www.secrethistoryofstarwars.com). Not much, but I hope it gets some awareness out there.
I've got the petition in my sig on other sites, and encourage others to do the same.
