No, it's just that the freak can't make himself well understood.
If you look at the link where he gives instructions on enabling 'extras' (http://maemo-freak.com/index.php/hac...vel-catalogues) you'll notice it's actually about extras-testing and extras-devel
If you're new here, this is what they're about: new software goes to devel, then to testing. Only after testing and approval by users can software go to the main extras repo.
You can enable these repos from you app manager if you want. Be warned that the software inside is not guaranteed not to destroy your device. Even if you only install these plugins, be sure to disable them afterwards, to make sure you don't accidentally install something from there later on
Have fun!
