Newsroom Publisher is one of the main reasons people choose Athena Portal Manager. It is the only tool on the market to combine so many different channels in one interface. If this fits your situation then look no further! On other CMS systems these components are all seperate tools. If you don't need all the channels, such as SMS, you simply remove it from your publish modes list. Newsroom Publishers is great for:

• Newsletters (email)- send the latest news to all your members .
• Newsfeeds - either RSS or Atom format. Newsfeeds have gone mainstream with Internet Explorer 7 now having an integrated newsreader.
• Podcasts - think of Podcasting as a newsfeed for MP3 files. Great for musician sites, realestate descriptions, speeches, etc.
• Vidcasts - video is hot. publish your videos using Yahoo's Media extensions to RSS.
• Text Messaging - send text messages from your site either on their own or as a way to alert your users to new content on your site. Great for last minute events.
• Calendar - the calendar can be used to access previously published items (think blog) but does much more! Great for posting events and seminars. Supports RSVP and export to iCalendar. 
• Blog - all the features you expect from a blog publisher; loyal readers can get your latest posts via, email, newsfeed or even text message.
