I'll second that, Carlos, Sunil - I desperately need the ability to sell ebooks in multiples - which is only possible when the user gets a single user id, and a single password number.
The reason: there would be no need to run each book before buying, and it would allow more spontaneous purchasing. That's important: visitors can select and purchase more books in one order. Catalogs become possible, and impulse buying because of specials, discounts and buy-3-get-1-free type sales can be encouraged.
Making it easy to select several ebooks and pay for them all at once when the urge strikes the shopper would certainly increase sales.
It would also increase the standing of Activ as a world-class compiler of ebooks (in my opinion), and entire ebook libraries.
Of course, those other wishlist items are almost as important, but this feature could be leveraged into a very profitable tool for massive library & info delivery over the web.
Apologies if I'm a bit cryptic, but I'm typing w/ only the left hand, as I broke my right wrist new years eve.
I'm not ambidextrous, just a dysfunctional left-hander...
