Call for translations !
Internationalization of eHour so far consists of a partial Dutch translation and localization of the date, currency and number formatting. For the next version the goal is to get as much translations in as possible. Although work is being done on the French and Dutch translation more help is welcome (also on improving the English text).

If you want to help out translating eHour in your native language go to http://translate.ehour.nl/ and create an account. In your profile select your preferred language and start translating !
At first you can only do suggestions on translation which are reviewed later on but if you drop an email at “info at ehour dot nl” you’ll be given access to do the actual submit.

I have to say that the user interface of Pootle isn’t the most convenient but it’s the only tool that I could find that does the trick, you might want to read Pootle’s documentation.
