ragnarlookbrood,
Congratulations on your Citrus collection. In regards to using Google translate, over the past 2 years I've done a lot of English-Russian translations. 2 tips that I use are doing a reverse translation to see if the results are still coherent and translating through a third language with which I have some familiarity (Spanish, or German in my case). If the translation transmits clearly and comprehensibly, I'm satisfied that it's an acceptable translation.
