That said, there are still a few bugs in the system. In my use, the biggest trouble spot has been the Journals feature. This is a spanking new option, not yet available in the Mac version of iPhoto, where you can create and publish photo albums. In essence, it replaces (and improves upon) MobileMe's soon-to-be-defunct Gallery.
Before delving into some potential problems with Journals, let's start with a bare-bones primer on how to create a new journal.
For this primer, I'm going to assume you are using the iPad version of iPhoto. The iPhone version has pretty much the same features, but a somewhat different layout.
1. Launch iPhoto. Almost every time I do this, an "Updating Photo Library" message appears; I assume this is not cause for concern.
