Hello Markus,
Thanks for the reply. I tend not to dislike sounds and tag them as such. From experience it happened several times that a disliked sound becomes a good one a year or two later in a different context. If I tag it negatively I could very well not hear it anymore, always ignoring it when browsing. So in this way a sound, a patch that has no score is one that's still 'open' for any kind of project, which might be different from year to year.
OK then, I'll edit the ranking files with emacs and use a macro to replace the number 3 with a 0.
Cheers,
Al
