and as time goes by, we end up with a huge list of unmaintained packages. :-(
this is where you can help. those packages are available. for you. for free.
have a look to the list. try to see if you're using regularly some of them. or even better, if you contribute to upstream project, either as a coder, or a translator. then claim your will to jump in.
you might fear that you don't know anything about rpm packaging. but that's the beauty of this campaign: the rpms are already created, and just need to be maintained. that is, update them when there's a new version, or fix a packaging bug. when this is the case (and assuming you have the rights to upload a package), a single command will update it to latest version:
$ mdvsys update your-package new-versionthen, update your system to this version and check if it works correctly. remember, you grabbed a package because you're using it - so you know whether the new version behaves as expected!
and if there is a problem that you don't know how to fix, ask on cooker mailing-list. there will be a lot of experienced people that will be able to help you. and as time goes by, you'll become more and more comfident, ready to package new software not yet available in mandriva.
now is your turn to chime in. come on, you know you want to do it...
