What is iWebSites? It is a program that enhances iWeb by manipulating the website files that iWeb creates to enable a user to create multiple websites that are completely independent of each other.
iWeb really was not designed with the power user in mind, but it does enable a user to quickly create beautiful web sites. With iWebSites, separate websites are kept independent of each other, and when sites are “published” to a directory (for uploading via FTP), only the site you are currently working on is published.
