If I can get a zip file with a good sample size of combat logs in the given language I can probably figure out most of it. I'm norwegian, which german is closely related to, and I had three years of french in high school (just don't ask me to communicate in the language, lol). If there are particulars not covered in the logs, I can just ask about those afterwards.

Other languages isn't my top priority at the moment. I'm working on this in whatever spare time I can find and there are still some other features I'd like to get in first (toggling concatenation of damage directions, reporting lists directly to the ffxiv window by pressing a button, small overlay window containing sp/h, exp/h and top 5 lists, xml export), but having the log files handy for afterwards would be a great help.
