The Hub isn't about MAS - it's about Magic Submitter, which is an entirely different tool by the same developer.
Magic Article Submitter is just an article directory submitter, and I no longer use it.
It only submits to Article Dashboard sites, that's it.
Magic Submitter submits content to ANY website - video sites, RSS aggregators, bookmarking, article directories, press releases, forum profiles...
It's an all in one tool. You can program anything into it.
