Add your Popular Tags in your magento frontend

This was a small problem but it was big to me
if you want to set your popular tag then first select the location where you want to add it (right or left panel) just go to the
app\design\frontend\default\yourtheme\layout\tag.xml

<default>

<!-- Mage_Tag -->

<reference name="right">

<block type="tag/popular" name="tags_popular" template="tag/popular.phtm">

<action method="setTemplate"><template>tag/popular.phtml</template></action>

</block>

</reference> </default>

find this code and change
if you want to keep it left then or leave it
