The rally is working wonders and as there are some days left for people to participate, this is a wonderful opportunity to learn what translating at translatewiki.net is all about.
I am happy to quote the mail send to our community for more details.
A few days ago I invited you to join our latest Translation Rally. Your response has been awesome – yes, you are awesome! Thank you. In the past 4 days, you have contributed over 34,000 translations for 20 Free and Open Source Software products. A volume we have never seen before.
The diagram on the right shows the number of active translators for the past 30 days. Yesterday, almost 70 different users have been active.
I want to call everyone of you to arms: show me you are still out there. Contribute! It does not have to be 500 translations, but just spend 15 minutes of your time to contribute now! I would love to see 250 active translators each of the next three days. I would be ecstatic if we managed to exceed 50,000 translations in the 8 Translation Rally days. I'm confident we can do it together. Again, again and again!
P.s. Did I tell you that we have a nice user page badge ready for those that qualify for a part of the bounty in a Translation Rally? Check out Olli's user page for example.
