Add Module position Next To User9

As the title,how can I add a module position next to user9/below User4?

You must edit index.php of template,

you will see this:

add position like this:

You must define position first in templateDetails.xml in above example it's named your_postion, by adding <position>your_postion</position> po <postions> XML element.

Ivan, thanks for this, however, I want the new position next to user9 (so, user9 left/new right). Your code puts it above User9!

I have been playing with the code for a few hours and cannot get it right!

You must restyle layout, we can not help you any further because you want template modification, you can request custom job.
