PUBLIC MARKS with tags plugin & management

Windows/Mac/Linux: Firefox extension Xoopit turns Gmail into a robust, searchable media management tool for every piece of media that comes through your inbox. By indexing every attachment as well as every link to photos and videos from sites like Flickr, Picasa, and YouTube, Xoopit allows you to easily search for and find any picture or video and view it from directly inside Gmail.

This plugin limits the user to publishing into the categories he/she is assigned
