I have recently been assigned to built a DotNetNuke web service to allow a windows application (or any type of web client for that matter) the ability to manage DotNetNuke user accounts (create, change roles, delete, retrieve email address, etc.).

Since I had a hard time finding a correct code sample or documentation that actually applies to DotNetNuke 7 and accessing it without being previously logged in to DotNetNuke, it was difficult to built anything. I finally found out how to do it correctly so I tough I would put my efforts to some use and write a blog post explaining how to do it step by step.
