Thanks to all for replying. I'm starting to understand. Perhaps I should wait and see what's included in the upcoming release? I've got lots of content that needs to be collected from old, soon to be discontinued websites. I'd like to bring it all together in one, very manageable place.
First of all, what is it? I've looked at the operation guide and didn't see any explanation of what it is. If someone could point me to a faq, or something, I'd be most grateful.
