If there is somebody who wants to continue (and I know there are a lot out there), please do. I will continue to work on this module, as soon as I have some free time.

Please read the readme file inside the zip.
It is not much, but it's a start...

It would be nice if we would make a sourcefourge project. Or maybe the core devs have the opportunity to continue my work
I am still mad at them for not modifing the user classes and tables. In this shop module, a registered user has to insert much more information than one does now.
