Since I had this kind of stuff, I asked for help in the Italian forum, and after finding a small guide explaining how to put it into a topic, I have changed, for the knowledge base articles.
---------------------------------------------------
Began:
Edit the file "kb_article_body.tpl" located in the folder "templates / default /"
Find:
<tr><td class="cat" valign="middle" align="center"><span class="post-buttons"> {EDIT_IMG}</span> </td></tr>
and replace with:
<tr><td class="cat" valign="middle" align="center"><span class="post-buttons"> {EDIT_IMG}</span> <a name="fb_share" type="button_count" href="http://www.facebook.com/sharer.php">Share</a><script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" type="text/javascript"></script> </td></tr>
Save the file.
Then you have something like:
The text "Condividi", I changed to "Share" in this how to.
you see the edit button, because I was logged in, and I am admin...
I apologize for my imperfect English, I am italian...
Thanks
bye
