Dynamic subgrouping in a news network

摘要

An apparatus and method for dynamically subgrouping messages in a news network is provided to assist posters and readers in the news network. Each message can be assigned one or more categories as well as being assigned one or more conventional newsgroup labels. Categories can have a hierarchical structure of categories and subcategories. Categories can be filtered and/or sorted by the reader and categories can be applicable to many different groups or specific to a group. The categories are not limited to any predefined list, but can be specified by the poster.
