RSSReader version 1.0.88.0 fails to open any RSS feeds from mojoPortal. I realize RSSReader is a third party program that you have no control over. I get the message "Feed contains an unexpected RSS or Atom version number" when trying to open a feed from mojoPortal.
This includes the current ones at:
http://www.joeaudette.com/RSS.aspx?pageid=1&mid=4 and http://www.mojoportal.com/RSS.aspx?pageid=2&mid=19
RSSReader can be found at http://www.rssreader.com. I understand that I could use another reader, but wanted you to know of the problem.
