Hi Giszmo, from the amount it is your refund for the Hindi, which was only partially done.
I have written up the details at:http://multibit.org/bounties.html
I posted the URL on the multibit thread but forgot to post it here. Sorry.
Bounties work but they are a bit time consuming to do (as you can see from that bounties page!).
Also, the most prolific translators do not want the BTC - they just want to see the software in their mother tongue. (MBH, who did most of the Arabic, donated his share back to multibit.org. Thanks!)
There are a few translators who have not yet sent me a bitcoin address for me to send their share to but that is no big deal. The BTC is not going anywhere.
