Hi, I'm new to k2.

Created an item to test k2 installation, and it doesn't appear only on front-end.
Items created previously on Joomla only appear OK.
I have imported the data from Joomla already.

Author publishing status:
Language =all
Access level =Public
Creation date = 21013_08_19
Start publishing 2013_08_18
Finish publishing =empty

What else should i check

Additional Data:
Joomla Version: 2.5.14
K2 Version: V2.6.6

Did you change the Homepage menu item type to point to your new K2 content?

Thank You, that's the problem.
I said I was new to k2.


PS:

A Beginners manual is needed.

Background:
1- I have a Joomla site published.
2- While i Do not know enough of K2, I want just to vamp, the appearance of my site.
3- I need to know :
a) how to setup k2 to switch from standard joomla appearance on front End.
b) how to change the appearance of home page, to an impact page.

4- I don't have much time to learn everything immediately, I have to learn as I go, but I need my site to remain online.

You could watch the following OSTraining videos to help you understand K2.
