It is not entirely clear to me just how Yahoo! Groups is limiting their functionality although it sounds rather ominous (especially after December 14th). Out of an abundance of caution, I have taken the liberty to *very quickly* archive everything that was in the "Files" section (except for the QS dictionary which my anti-virus rejected for reasons that I am not sure of). It is in a 7-Zip file and located here:

It would be advisable if there were other places for the archive to be kept besides the location listed above in order to prevent the archive from being permanently lost. Please post those locations here and, perhaps, the Reddit group so that others may still have access to them. Thank you.
