Hi, there is a pull request pending on OST github... With internationalization.
https://github.com/osTicket/osTicket-1.7/pull/288(https://github.com/osTicket/osTicket-1.7/pull/288)
and a .PO file with all strings.. but for RC3 at the moment :
https://github.com/interlegis/osTicket-1.7/blob/develop/i18n/templates/fr_FR.po(https://github.com/interlegis/osTicket-1.7/blob/develop/i18n/templates/fr_FR.po)
I don't know if developers tends to import this project into OST 1.7 ST, but they could have a good basis if there already are translations...
