The general idea of teaming up to address issues/bugs or add features is some sort of hackathon.

I'd be interested in attending, and I don't mind taking some time to
help organize.

Some of us have also been talking about planning an OpenBSD-style
hackathon.  (OpenBSD hackathons: Get developers in a room, and write
code for a week, exchanging ideas, trying to get commits into base and
ports.  Beer is usually involved.)

We'd discussed putting together something like that for Plan 9 in the
first half of 2020. Anyone hacking on Plan 9 related code would be
welcome.

I don't know if this is a different suggestion so much as a different
event.  Experience implies that merging the two together may be a bit
too much in one shot.

Expect a post about that when we start sorting out the details.
