I've spent a fair amount of time bending Mathematica for taking notes and I've been very happy with it, the only missing piece it seems is a nice spell check dictionary for Polish (my mother language).
If anyone could point me to the right resources; where to download or how to convert an existing dictionary to one compatible with Mathematica I'd be very grateful.

Alright, so I've recognized that the spelling dictionary probably sits in
Mathematica/Contents/SystemFiles/SpellingDictionaries/English/Mathematica.rws and I've found some clues that it might be an aspell dictionary, so I've downloaded an aspell polish dictionary from http://sjp.pl/slownik/en/, builded it to .rws (here's a zip) and then tried to replace the default English dictionary (because putting dictionaries side by side in
/SpellingDictionaries didn't work either) and when I've tried to spell-check a document the box reported a problem with Mathematica.rws which probably is CodeSigned and therefore cannot be easily replaced...

The first 32 bytes look exactly the same so the format should (?) be correct.
Well, I guess we may be left stuck just one last step to a working solution.
