Plus, with out .mac, you lose some cool iWeb functionality. For example, it appears that the pretty slideshow only works on a .mac hosted site.
I'm using my .mac trial right now...trying to decide whether to give it a go, or to just continue laboriously uploading. What I need to figure out is if there's a way to only export pages that have been updated. For example, I'd like to mount the server, and then hit exportand have iWeb only export items that I've changed (as opposed to exporting and uploading the whole thing).
