My family has a tradition of opening one gift on Christmas Eve. From Blackboard this year we have the gift of our Vista CMS back up again. (Actually yesterday late morning).
You should be able to log into your Vista classes again now, using the same URL - Online.CCCOnline.org. (CE server uses the instructors url between terms, the exact link is in an old blog post.) If you see the BB screen instead of the Vista login screen try clearing your cache, deleting cookies, or a different browser.
Have a wonderful vacation!
