Great! Joined.

Do you know if these people have connections to anyone who'd be willing
to help implement structural editing for current systems? I could
(really) use collaborators or advisors, and it'd be a shame if lessons
from Interlisp were lost in new systems. I can just ask on that list if
it's not considered rude.

Have you tried Airship Scheme / is it actively maintained / soliciting
contributions?
