Hello and welcome @tasharnreid 
The main website got a big update last month, and The Great Big Review and Testing Guide hasn’t been updated to match yet.
Don’t worry though, the Tester programme is still running. For now, all the Testers (secret and regular) are all being posted in the #testers category, and you simply have to read the topic OP and pop a reply in with the items you’d like to be considered for. 
(The 
ones are regular testers, and the 
ones are the secret ones)
The Great Big Review and Testing Guide still has some useful stuff in, so probably worth a read anyhoo - just mentally edit out the bits about the Tester List, Sex Toy Tester Wishlist, Linking profiles, etc that were all part of the old site structure. Hopefully it will be updated soon.
