Putting string theory into practice
In order to present a consistent user experience to our users we ask that external developers use the same strings in their user interfaces that we use in the Skype Client. To make this a bit simpler for you, we have published a list of almost 2900 phrases in 28 languages — and licensed this to all developers under the terms of Skype Component License.
Kudos to Peter Kalmström and the kind folks at the Skype Localization Team.
