@Shrub: I think JCSS is a group of people who buy Jade DVDs, rip them, and share them amongst themselves online. To join you have to also start buying Jade DVDs and sharing them with the group. At least, that's what I heard.
I usually just use jdownloader and let it run overnight. Sometimes it takes a few days to download all the vids I want from colweb's weekly dump, but I can wait :)
As for the "little trick", you're right, it seems like a bad idea to share it publicly... :/ but you can always PM me :P
