When you create pages in PHPFox you have the ability to login and interact with that page, AS that page. This article will show you how to do just that.
Login to your PHPFox website, not the admincp, but your website itself. Click on Account > Login as Page in the top right menu bar.
A pop up window will appear with a list of pages that you have created. Click the Switch button for the page that you want to login as.
You are now logged in as the page, and will be able to post blogs, images, and anything else to the page AS the page!!
To log back out into your account, you simply need to click Account > Log back in as (username) in the top right menu.
