Hi Arno and Colin,
many thanks for the attempt to help.
In deed it seems to be a bit complicated, so I will try explain better:
We have two pricelists.
list "A" for traders and list "B" for gardeners.
Both lists are located in category "Preisliste" and accessable for everyone (in present). Now I want to restrict acces for both prieclists, so that only see traders list "A" and gardeners list "B", if they are registrated. I also want to invite new clients to download their list. But they will not register, never. So they don't have acces.
I wonder if there will be a possibility to send something like a key with the invitation or a special direct link. It must be easy to handle, automatically, no regeistration, no two steps or something what is more complicated than doing just a click.
thanks
Alexander
