All the information iWeb needs to create your websites is in one file known as the Domain file. In iWeb 1.x, this file must be named "Domain", but in iWeb 2 or later, you are free to name it anything you like. For the purposes of this discussion, we assume that the file is named "Domain." You can copy this file from computer to computer so that, for example, you can work on your site from home and at work.Beginning with iWeb 1.1, you can now select a new default location for your Domain file.
