Can you publish only 1 site on .Mac

Question

I have several websites on iWeb and only want to publish one site on .Mac. Can you do this?

Answer 1

As Jim MacCormaic describes, and Apple's tech doc, the Domain file that was most recently double-clicked is the default file used if iWeb is subsequently launched directly from the iWeb application icon, as when launching from the Dock. But note that the file must always be named exactly "Domain", so you'll have to keep them in different folders, for example, with the folder names describing what they are for.
To continue working with multiple Domain files from the Dock conveniently, you could drop the Domain files onto the Dock, and click on them in the Dock instead of directly on the iWeb app icon, to launch iWeb. That would allow for quick switching. Maybe you could create an alias to the "Domain" file, give the alias a better name, and then drag the alias' icon into the Dock. But those icons have to be in the documents area of the Dock; they can't be dragged into the apps area.
Another option might be one of those UI tweaking applications. I seem to remember one that added to the popup menus that appear when clicking on app icons in the Dock, including adding recently used/opened documents. That would allow you to right-click on the iWeb application, and select your Domain file, or maybe more distinctly-named aliases, from the popup menu. This would require adding the UI tweaker to your system, and running it at login, but it would keep your Dock clean, at just the one iWeb app icon.
