You can give invited guest authors the ability to publish their articles within a specified section of your site.

Building a big content rich site all by ourselves can be tough. There are only so many hours in the day, and each of us only knows so much.
Your Page-Engine account can help by making it easy for you to collaborate with other authors.
You can set up Guest Author Accounts for invited columnists, which allows them to publish, and edit, their latest articles right on your site, in real time, without your help.
Here's How It Works

Let's say you have a site about squirrels. A friend of yours is an expert on squirrel rehab.
You create a category on your site called "rehab".
Then you create a Guest Author Account for your friend, so she can publish and edit her articles on your site within the rehab category at any time.
You're In Control

The Guest Author Account limits the guest to publishing and editing within one specified category of your site. They can't touch any of your articles, or control anything about the way your site looks or operates.
You give the guest author their own password, so they don't have access to your account, only to their own limited control panel.
You can turn guest author accounts on and off as you wish.
You can change which category the guest is approved for.
You can create as many guest author accounts as you need, and delete them when they are no longer needed.
You can edit or delete articles by guest authors.
If necessary you can delete all of a guest authors work with a few clicks, by deleting that entire category from your site.
Multiply Your Possibilities
The search engines like big "authority" sites.
Imagine trying to create a 1,000 page site of original content all by yourself.

Yikes!
Now imagine building the same site with a team of fellow experts, each of whom is publishing on their own (under your supervision) in their own section of your site.
Phew...
Publishing a large site just got a lot easier.
Of course the more content you have on your site, the more exposure your site has in the search engines.
Thus, more traffic to your site, and the articles you're writing.
Congratulations, you just got promoted from author to publisher/editor, and can now run a real magazine on your site.
