Redmine

If you have a wiki, you can't use the same page with differents translations.
You must create another page for each translation.

Example:
- Readme (in english)
- FrReadme (in french)

If one user access to your wiki with a « french browser », this user will see a redmine interface in french, but the content of the wiki will be in english.

This user must click on FrReadme link to access to the french version of the page.

I have a proposition, on wiki page editing, add a list like the « target version » list available on issue editing. By default, the selected language is the application default language.

So, if the administrator will translate his page in french, he can:
- he clic on the add button,
- he select a translation language,
- and redmine will show a blank textarea field.

Administrator manage one page.
User see the page in his language (if it available).
