Quote by Yves:

Okay, this is undocumented, I think. Yes, the Reference item was supposed to show what translation yours is based on. Mine are not based on anything, I wrote them new. Yours is then based on the English translation. You could write the language you're translating from and the last edit date of the base file, so that you can easily compare the English file with yours and see if something has changed (only by comparing the date).

Quote by Yves:

You wrote a last edit date in your files. This was 8 digits, with no separators in between. If you do that (like I do), nobody will have a chance to know what digit has what meaning. Where's the year, where's the month and is it a date at all? The only way to be sure about that is the only way to make it comparable by numbers. The biggest value first, the smallest last. That is the format YYYYMMDD (year, then month, then day).
