The default Joomla templates only provide 6 or below Module positions, not very good if you use the loadposition user# feature and want to load modules in with your content.
The answer is easy enough, usually a 5 minute process of editing a single file, as follows:
Open your active template(s) directory and open the file(s) templateDetails.xml in a plain text editor or using your hosts control panel File Manager (preferred).
Scroll down to the beginning of <positions>, and add in as many positions as you like. Here I've added in another 6 from lines 11 to 16:
Save the file(s), refresh your browser twice and you should see the new positions available when editing modules. You can then use the new positions without having to worry about conflicts with defaults.
<positions>
<position>breadcrumb</position>
<position>left</position>
<position>right</position>
<position>top</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>user10</position>
<position>user11</position>
<position>footer</position>
<position>debug</position>
<position>syndicate</position>
</positions>
ok, so above we have added and informed joomla of 6 new positions.
BUT, how do we place them in the different positions??
eg. user 11 to 13 under user 1 to 3?
user 14 under user 11 etc.
