I was wondering about this stuff and couldn't find a thread on BHW about this. If you do not know about WDF and IDF, I added the following section with a quick explanation. My question is: Has anybody tested this long term? And if so, are there good tools available for it? I'd especially be interested in a tool that can differentiate between languages (google.com/.fr/.co.uk/.de). since all the stuff I'm using now is set on a specific language. If this stuff works, writing texts could be optimized a lot.
