OK, since there seems to be no support of any kind any more, here's how to change your theme to an invidiual one:
1. Duplicate the complete folder "default" including all subfolders within the folder "themes". Rename it to a name of your choice, eg "foo".
2. Open [pommo dir]/inc/classes/template.php and change the value of _pommoTheme in line 32 to eg "foo".

If your are - like me - more than unhappy with the translation strings, go into the subfolders "subscribe" and "user" of your theme directory, search for strings between {t} and {/t} in the .tpl files and replace them by a senseful and appropriate translation. Don't forget to delete the {t} and {/t} afterwards.
