I started again with the dutch translation of the frontend en checked all the 1296 lines of the 3.17.1 version.
Before using it I woukd like to know if these are the complete number of lines for translation.
Thanks for your reaction and no, I'm not translating from scratch. I took one of the .ini files completed the translation of some lines and mended some (sorry to say) crooked dutch.
I already found the other language files and start checking this real soon.

I've just sent the dutch translation for the frontend. I will start checking the part for the administrator soon.
And, Joris, It's possible the translation is not 100% correct but better then it was. I sent the ini file herewith so you can check. Comments wil be helpfull.
