One of the great features of Adobe Digital Publishing Suite is the ability to share folios that you create with a select audience of reviewers, approvers and collaborators. Here are a few things you need to know about this.
1. When you share a folio, you will be prompted to enter the email addresses of those with whom you wish to share the folio. The email address that you enter here MUST be the email address that the person used to sign up for their Adobe ID. In other words, if you routinely correspond with "John" at firstname.lastname@example.org, but when John signed up for his Adobe ID he used his gmail address email@example.com, you will need to share the folio with the gmail address.
This requires you to ask your collaborators for the email address they used for their Adobe ID, OR they will need to create a second Adobe ID to correspond to the email address you share the folio with.
2. If you want to see who you've shared a folio with, select Unshare from the Folio Builder panel menu. This will present you with a dialog box listing all the email addresses you've shared a folio with. You can then just click the Cancel button, and the shares will remain untouched.
3. adobe.com/membership is the best place to create new Adobe IDs, to test your Adobe ID to see if it works, or to change your Adobe ID password.
