I am not fun with this type of listing.
I would prefer each language in a separate directory having the following subdirectories:
LANGUAGE X
- Core
XOOPS Version 1 / pre final version a, pre final version b, ..., Final Version)
XOOPS Version 2 / pre final version a, pre final version b, ..., Final Version)
...
XOOPS Version X / pre final version a, pre final version b, ..., Final Version)
- Modules
Module A / pre final version a, pre final version b, ..., Final Version)
Module B / pre final version a, pre final version b, ..., Final Version)
...
Module X / pre final version a, pre final version b, ..., Final Version)
- Themes
As above
This way is much easier to find what is available (or missing) in your preferred language.
Regarding the Mirror sites, I believe that more than 2 is too much. After sometime one or the other will be forgotten.
SF.net seems to be a fine place for developers but not for translators.
