In my recent survey MediaWiki's bugzilla settings, the maintainer and
developer for the Proofread extension has told me he doesn't have time
to work on the extension any more.
Given that this extension is essentially the life of WikiSource, it
desperately needs someone to take over if WikiSource is to continue to
grow.
I would personally like to see MZ McBride's Bug #28893 fixed (“Proofread
Page extension needs an API module to retrieve page status” —
https://bugzilla.wikimedia.org/28893). If an API were available, I
think that we could begin to use it as a replacement for Google's
reCAPTCHA which does not make the resulting texts freely available.
If you have any interest in helping out with the extension, please check
out the list of open bugs:

Thanks!
Mark.
