We have made osTicket 1.7 i18n with its full spanish translation and a module to manage the creation and the edition of new languages.We dicided to make osTicket supporting multi-languages because it was a need of the company
that we work for and now we want to contribute with osTicket community.
Our modifications are:
-Integration of a module to manage the creation and the edition of new languages(It doesn't need to be installed).
-A full spanish translation integrated with osTicket.
-An option in the osTicket configuration to change the osTicket language.
