Yes, I need help creating the actual page. I know how to create a custom page, but the USERCP page seems to be different.
The USERCP template is a template which inclure the header, the navbar, the USERCP menu and the content space.
So your new page had to implement the USERCP template
(like is described here). So it isn't a simple custom page which include the USERCP menu.
My question, is how to complete the content space?
