For the sake of clarification only...

Any substantial (largely complete) code contribution to DotNetNuke must be accompanied by a "Software Grant".  Essentially, this provides for the ability to have dual copyright by both the original contributor & DotNetNuke.  This means that the contributor is protected because they can continue to do anything they like with the code without restriction (which includes commercial use).  However it also ensures that it can be included in DotNetNuke without "tarnishing" our BSD license, which protects all users of the DotNetNuke platform.

We do ask all of our Project Leads NOT to engage in commercial development (retail) of DNN applications that are like the project they are responsible for.  This is simply to avoid any appearance or possibility of conflict of interest which might arise from "holding back" on a project due to competition with their own offerings.  However, many of our Project Leads engage in commercial development (retail) of other modules and also enhancement of their projects for custom use, which generally winds up back in the Projects (and provides broad benefit).

Scott Willhite, Co-Founder DNN

Thanks for clearing that up Mr. Willhite. 

As a user of the platform, now I can sleep much better knowing that you are keeping people from "tarnishing" the DotNetNuke BSD license.
