On the joomla 1.0.x series we could add new module positions on the joomla installation via Template manager- module positions (total 50 places).
How can we do this in joomla 1.5 ?

In joomla 1.5 you have to add the module positions within the templatedetails.xml

<positions>
<position>hornav</position>
<position>breadcrumbs</position>
<position>banner</position>
<position>left</position>
<position>right</position>
<position>top</position>
<position>search</position>
<position>topsl</position>
<position>user1</position>
<position>user2</position>
<position>user3</position>
<position>user4</position>
<position>user5</position>
<position>user6</position>
<position>user7</position>
<position>user8</position>
<position>user9</position>
<position>footer</position>
<position>syndicate</position>
<position>debug</position>
</positions>
Simply add another line(s) with <position>your module position</position> and place it in the order it will appear within the list
