Ok, I picked up CB Content Module and have set it up. I now see the problem.
I see one method to pass in the desired username, by using the url to perform a database lookup, within the module, for the username associated with the article. Not a very elegant solution, but I don't want to add usernames to my GET/POST data.
I have a bit more problem-solving to do, but thank you for the help krileon. I can now see how to get the job done once I find a better method of passing the information.
