Subject Re: E-commerce recommender, recommendations for users who are not logged in?

Hi Kasper,

The Ecom Recommender (
actually does have a basic way to handle unknown/new users, they get
recommended generally popular items.

I think the Universal Recommender might suit your needs best though. You
can find out more about it there :

And yes, AFAIK the blacklist option will simply filter out any items you
pass to it.
