I have a site that I made with iWeb on my iMac. Now I have a second Mac, a Mini, and I am trying to use it to work on my site but I can't figure out how to access the current site with iWeb. All it seems to want to do is create new sites. My site is saved to the "Sites" folder on my hard drive, and uploaded to my MobileMe space. Yet there doesn't seem to be any way to open the site, from either location, with iWeb on the Mini. Am I missing something obvious?
