Nice to see this story from lifehacker naming RSSOwl the best news reader for Linux.
You can find instructions on our Contribute page. Thanks in advance!
With the same mechanism, you can even install additional languages into RSSOwl. Find the list of additional languages from Tools | Language | Download Additional Languages.
We added Italian and Polish versions of RSSOwl and there is still more languages to come soon. If you are missing your spoken language in RSSOwl, you can help out in translating.
Mac users will be happy to hear that RSSOwl for Mac is now provided as disk image. In addition to this new deployment format, the application is now a single executable application bundle that can easily be moved to the applications folder and started from there.
Finally I would like to point out our new repositories for Ubuntu provided by getdeb.net. More details are available from our page. Note that packages.rssowl.org is no longer actively maintained.
We are still looking for more people helping out with translations. If you can help us, please click here for further instructions.
Update: Localized versions of RSSOwl are now available from our downloads page.
