As part the docs aspect of this, I've made a story in storyboard,
and then added tasks to it as a I did a very fast (and incomplete)
review of the existing text files that we tend to include under the
umbrella of docs. There are 16 or so vague tasks which probably need
I wanted to be sure to get these tasks written down, so I used
storyboard, but I'm not sure that the way I did was the right
choice, but it's start .
I hope that as group we can start addressing these next week.
Feel free to assign a task to yourself if you're able, and add other
On the member-of feature, I remain inclined to include it if we
agree a) it is low impact, and b) that strict adherence to
feature freeze in a project as simple as placement, though
important, is less important than it is in something like nova. I
agree with both of those statement, but we should figure out what
the whole group thinks and go with that.
I won't be at the meeting on Monday (funeral), but that ^ registers
my thoughts on the matter. I hope people will figure something out
and also make some doc and other release-related plans.

For me it has less to do with something waiting on it, and more to
do with making things available as they happen.

That's fine from my standpoint. My default position is if we have a
chance to get more stuff out we should try, but if we don't,
especially if there's not a lot of clamouring that's fine too.
In fact clamouring-oriented-development is probably a good strategy.

Thanks for that, looks like some potential. I have no idea how
people keeping track of all the change in our nearby universe
lately. At least we have pupdates.
 Adapting to storyboard is going to involve a lot of
experimenting. I think we can make good use of it, but it is
different from anything else I've used. To some extent it is an
abstraction that one can manipulate as one likes. That makes it
potentially powerful, but probably challenging for people who just
want to report a bug. We will almost certainly need to do more
triage than we've been used to in placement in the past.
