There aren't a lot - which means it should be pretty easy to follow the ones there are, hmm? Here goes:
1. You have to like Jacen and Jaina Solo, and particularly their "twin bond" (because really, how fun is that?). It seems obvious, but there it is.
2. You need to have a name (any name you want, as long as it actually resembles a name/handle) and an e-mail address.
3. If you have a website, stick a link back somewhere.
4. If your website is a hate or porn site, please don't bother entering the URL, because I won't link to it.
Got it? Good. Go join!
