If you like my comic so much that you're willing to risk losing some of your audience to me, you can send me an e-mail. You don't really need to ask for my permission, just let me know that you have a link to me on your site, so I can see your site. I can't promise anything about linking back to you, but I do promise I will take a look at it and if I like it I will link.
Please COPY my banners--the image files-- onto your space if you want to use them. Do not inline the images from my site. It won't work anyway.
