Right now related articles block is placed on left column of products page. Can i move it to main column or place it on tab the same as at templates-master.com
Certainly, you can. Please open knowledgebase.xml and find next block:
<catalog_product_view>.
Then you should change:
<reference name="right "> to <reference name="content">.
You can also place that to Easytabs blockwith following code.
<action method="addTab" translate="title" module="knowledgebase" ><alias>knowledgebase_tabbed</alias><title>Related articles Questions</title><block>knowledgebase/product</block><template>knowledgebase/product.phtml</template></action>
