Update: Bob was gracious enough to send me a copy of the paper. I guess he already has an account with Burton.
When you are trying to 'Access Complimentary Content' from Burton, such as Bob Blakley's relationship whitepaper.
I'll leave it to somebody else (who may not have the same great amount of respect for Bob that I have) to point out the irony of Burton trying to establish a 'relationship' with me based on justification as tenuous as downloading a whitepaper.
Can somebody send me a copy of the paper?
