I wanted to do a tutorial but it was very long : that's why I made an extension !
This extension is small because it only applies template modifications :
- Download and unzip it.
- Copy the src/addons/SyTryC/AccountWrapperFA directory to your server.
- From the AdminCP install the add-on.
If you want the template modifications as a tutorial, just tell me. If you have question, ask me !
