I know they were having server issues but the sites been gone now for almost a week. Anubis org is the site I'm talking about, I know there are other AnonIB's but they charge people to join.
anonib (dot) al is the anonib you're looking for. They just added a domain to their servers. They also have anonib (dot) su as a backup. The other anonib forums are paid sites, and they charge you to see the archived content of the original anonib.
