Once you're done cruising around nonvideriDesigns, I suggest you visit these sites first and foremost. They are, in my opinion, some of the best sites out there, run by some of the best people. My short descriptions won't do them justice, so you'll have to see for yourself. Go ahead. Click a button.
...but you can still try and when it opens, I'll keep your site in mind. =]
If you would like to affiliate with nD, just head over to the contact page and fill out the form there. Put 'Affiliation Request' as your subject. There aren't any specific requirements besides being a graphics/art site; just remember, quality over quantity, and though you don't have to update regularly (as if I do), show you're dedicated to your site. That's all. If you must have some guidelines, I especially like sites with strong, smooth coding to complement the graphics. I'll reply to let you know what I think. Best of luck to you.
