Community made a great job this month. Microsoft MVPs have localized Team System Web Access (TSWA) into 7 new languages. With support of Microsoft Turkey, Hakan Eskici (TSWA Program Manager), Tufan Erdinc, we have built the Turkish language pack. The full list of language packs are below.
To download any of the language packs that you are interested in, visit Team System Web Access Localization Project on CodePlex.
