Within sitefinity there is a build in control that will register users and add them into the sf_sitefinity_profile table. I been looking for that line of code but I am unable to find it. Is there anywy I can find it? I can't see the controller for this register users control is that in the project?
You want to probably do that stuff in the UserEvents not in a control.
