I don't think you need to be a registered user on the sight in order to download builds. anyway here are some links from Neopeek's sight.
[New Test-Release][CyanogenMod6] | Neopeek - Network
[ROM][FroyoRedux-Port][CM6] | Neopeek - Network
just click on any of the mirror links in the first post and you should be able to download these builds.
Keep in mind that these builds are not final and are still under testing. They seem pretty stable based on the users posts.
