I put a Catalan page on my website (FAQ's) if anyone would like to cast an eye over it and maybe report serious errors. On-Line translations are getting better but it is bound to have errors.
The person who might have helped has been too busy and I surmise his fluency is at the same level as Babylon/Goggle (sic).
I met a Serb lass and a Slovenian guy so pages are there too waiting for another meet-up to see if they are willing to peruse those pages.
Mostly simple word/abbreviation explanations.

TIA
