Download Dictionary Text File and Add to Personal Word List?

[DavidR]

In response to a related question, MM suggested this:

If you have an “allowed” word list, you could hack this by setting up your personal word list (which is just a plain-text file, saved at %LOCALAPPDATA%\Scrivener\Scrivener\wordlists.ini) with all those allowed words…
The wordlists file is just a comma-separated list of words, so you can bulk-edit it easily. Add a single word to the list via Scrivener’s interface (from the Corrections options) to start, so the file is created; then just modify that directly in a plain-text editor and restart Scrivener to work with it…

I did this with complete success using a spelling list I had developed in another program.
