I'm very grateful for all the work that so many people have done to see that Tellico is translated into other languages. The most up-to-date statistics on the translation for Tellico are available from the KDE i18n site. A recent snapshot is shown below.
If you have updates for the translation files, the easiest thing to do is to contact the KDE translation team for your language. If you have KDE SVN access, please commit them yourself, or if you'd rather, send me a patch by email.
