I installed K2. I imported articles for it to edit. However when I save th changes the article is NOT change. I noticed in Joomla JCE is listed as the editor. How do I get K2 to work?

K2 is not an WYSIWYG editor. K2 is a component which replaces the default article system.
These videos will help you get started.

Thanks for your response. I followed the video carefully. However I get a very different result than the video shows. For example the attached file shows my screen when I select control panel. It is different from the screen in the video. Further per the video if I click on the K2 tab I should get a screen with K2 things on it like dashboard etc. However when I click on the K2 tab I simple gt a list of articles.
Any idea why it is different than what the video shows? I can't seem to find the dashboard for K2 anywhere Ilook.

The only difference is that the videos are showing K2 in Joomla! 2.5 while you are under Joomla! 3.3 . There is no dashboard in K2 anymore. However the functionality remains the same. What's exactly the issue you are facing?

Thank you for the response. I was just curious why what I had was different than what the video showed. Thought perhaps I had not installed things properly.. No specific issue other than that.

You are welcome.
