    SkypeInYourLanguage

    Skype language files for additonal languages (details below)

    PLEASE NOTE So there is no way of making the current Skype accept the .lang file. You cannot run a version older than Skype 7 and even installing 7-8 is fiendishly complicated because it forces everyone into the app unless you run it in compatibility mode. Time to call it a day. I will back up the current files and then shut down the project at the end of the month. Please make your own backups from SourceForge because I till take that down too. If anyone wishes to take it on to handle just the Linux part, please give me a shout. Thank you for all your hard work over the years and really sorry to see this go but it's probably time to find an alternative to Skype that's localizable and OS.
