The move to a new server has gone well and is almost complete. However, there is one major issue that is leading to a lot of confusion.
The links have changed. This means that the tab number for the videos page and the RSS feed have changed. Therefore, old emails with the link to the videos page are no longer correct. Any links to the RSS feed are also broken.
The link to the videos page is now:
http://www.learnmicrosoftbi.com/Videos/tabid/75/Default.aspx
The link to the RSS feed is now:
http://www.learnmicrosoftbi.com/Home/tabid/37/rssid/1/Default.aspx
Note that one of the side effects of this change is that if you click on a link that points to the old video page, it takes you to the login screen. When you log in, it says you are not authorized to see that page. Do not panic! Click on the Videos tab and all will be well.
Finally, expect the forums to be back up within 2-3 days.
