Joining is free, but you have to follow a few rules:
1. Be a Jack Black fan. :)
2. Provide required information: your name (or nickname), a valid email address and country. You won't be listed if one of those is missing.
3. A site is NOT required, but if you do have one, you must link back using a code or a text link.
4. NO hate, porn, illegal or similar sites. If you have a site like that, you will be added, but without a link to it.
That's all. Join now?
