is there any posibility to figure out which <div class="..."> in the source code (to see in the browser) stands for which module position?
For example, something like <div class="user4"> [Modules of module position User4] </div>?
I'm qhite sure, that every module position has a surrounding div - isn't it?
Best thing to do is get Firebug for Firefox plugin. Then use it to mouse over your live site and look at the code. If you are mousing over the right column, then you can look at the code as see how it is identified in the template's index.php.
