Symphony.

I've seen a few people talk about publishing a website as an online magazine (by the issue), some of the solutions where good, but not ideal.

This extension includes two new field types:

• Issue Number: An auto incrementing number field that only accepts unique numbers (so you can't have two issue #2s).
• Issue Link: Lets you link to sections that contain an Issue Number field, automatically selecting the latest issue.

Both fields can be used like a standard Symphony field, for example, you can group all of your entries and sort them by issue.

Cool!
