My #1 Tip, no matter WHAT you do online, CBU or otherwise: Stick with it, don't just jump around from one method to another if you don't find success right away. It took me a good YEAR to get my first Affiliate sale, but I also wasn't following any particular training, and was just jumping around from method to method....so I do have a bit of experience there and know what i'm talking about. :-)
As for being OVERLY positive, as you said, I don’t really get that ‘feeling’ when browsing their site. I expected to ‘see’ them ‘shouting from the rooftops’ about how awesome CB University is (based on your comment), but didn’t really get that feeling. It just felt to me like they were trying too hard to come off a real review, despite it clearly not being one.
It CAN be worked with the basics but it will take you a long time to get them working using a host sublinked website and just 2 before you have to pay for your domains which one should want to do even for the 1st two so you do not have the long sublink. I wouldn’t buy from a sublink. I would think it is a trap or a “sneaky” website more so than a “trusted” dot com site. That is why it is ALWAYS worth paying the $11.99 or $12.99 for the domain registration, for the MILLIONS of people like me in the computer security field.
