iWeb "Out of Space" question
Your iDisk has 20GB of space. Unless you change the defaults 10GB are applied to storage and 10GB to email. It's possible you have used all the space for storage and still have 10GB available for email. I have my settings to 18GB for storage and 2GB for email.
If that is not the issue contact Mobileme chat support and they can determine what the problem is.
Here's a photo of where to look for the settings.
Whatever you can do, or dream you can, begin it. Boldness has
genius, power and magic in it. - Goethe
