TestLink has had a partial Dutch translation since 1.8.0. I have now completed it, and added translations for the functionality that arrived between 1.8.0 and 1.9.4. At least, I have completed the 'normal' user interface: a few areas such as the audit log and server errors I haven't yet done. Probably they aren't much needed (most Dutch admins are familiar with English), but I could do these some time if anyone needs them.
The translation will be available in the next release of TestLink. In the meantime you can download the Dutch translation from http://sbpoley.home.xs4all.nl/testlink/nl_nl.zip Just unzip the file and copy the contents to your TestLink directory locale/nl_NL. I haven't deleted any of the obsolete strings, so these files should work for all versions of TestLink releases 1.8 and 1.9.
Errors spotted and suggested improvements can be submitted via Mantis as usual.
