It isn't a spamming facility... As I said, she simply went from a static site to Zencart. Zencart has a email newsletter facility so she wants to add her contacts from the static site into Zencart then with her "new site launch" newsletter, she wants to add something to the effect of "to log into your new account, simply request a password" that way all of here already optin clients will have an account and she'll have 1 central place for their information rather than relying on 3 different 'companies' as she did before.
As to the multisite, that would work if he wanted one central hub. Basically, it is going to be a 2nd company with completely different accounting. He just wants to keep the design/categories.
Thanks tho
