I'm working on the latest Moodle 2.1 build and I couldn't gather enough information about how to add new strings to the Italian language pack (also English pack would be welcome).
These new strings are specific to my project (i.e. they're not already defined in native Moodle localization files) and I'd really like to isolate them in a specific file (e.g. my_web_site_strings.php) so I can better manage any kind of upgrade of Moodle or backup routines.
As far as I've read the docs online, I can surely customize the native Moodle strings, without any other tool to create new ones: am I right? If so, what's the recommended procedure to add new strings to a language pack? Please, use my case as example for the guideline (italian language AND english language).
Thank you in advance for your kind support,
