1. Your host must allow direct linking.
2. Your code needs to be up at all times. If it's not up when I go to approve you, you won't be approved.
3. No pornographic, warez, or annoying websites. Site with a lot of pop ups will not be accepted. Commercial websites can be submitted as well as long as what you sell is cute.
4. If you have multiple sites you can submit all of them but the code needs to be up on every site you submit.
5. Your banner needs to be 88x31. No exceptions.
6. The code needs to be in a visible place. The amount of impressions you earn is based on the amount of times the banner rotation is displayed.
7. Do not hide the code in a long frame or run scripts that automatically reload the page that the code is on. It's not fair to other members. You're using up their impressions and nobody is seeing their banners. :( It's fine to put the code on a page that gets a lot of hits, just make sure the code is visable!
8. Your site must be in English.
