This category is for providers of services, generally on-line, so users may receive messages transmitted in multiple formats to a single subscriber inbox. It is further intended for first-tier providers. Those re-directing or providing second-tier services will not be listed. It is NOT appropriate for shareware, nor is it appropriate for software-solutions designed for loading onto local or network locations. Spam listings (listing sent in bulk to multiple categories) will be deleted from this category without ceremony.
