SHARE a FOREVER Address Book

We need to be able to SHARE our FOREVER address book.
For instance, we have adult children who begin sending their own Christmas (and other) cards and need our address book. We need to make this simple to share so they will see how convenient their FOREVER account is. If I was deciding which company to use and I knew that with FOREVER I would not have to type in all my addresses, I could just get them from my mom or my sister etc, I would choose FOREVER over another company I was looking into simply based on this time/effort factor.

I believe SHARING is better that exporting/importing because an exported file can be imported to another company, unless the exported file is a FOREVER proprietary file type.
