Companies are bought and sold all the time. According to the terms, new management can impose whatever new rules they like. It's the nature of the beast. These contracts are written by attorneys to account for many possible/ probable scenarios in the future.

* Unlike HubPages, RedGage is not solely a writing site.
* RedGage is a social network type site like Flickr.
* According to the RedGage website, Red Gage "pays people for their online content and monetizes their social activity."
