+Hi,
+
+I've talked to Ben, the current Phabricator test setup would actually b=
+e=20
+usable for "production" use for task/project management for us, without=
+=20
+causing the sysadmins unreasonable trouble when migrating to the full=20=
+
+production deployment of Phabricator eventually.
+
+Phabricator project layout it orthogonal to repo layout, so we can stru=
+cture=20
+this however we want. Among other teams I see at least the following la=
+youts:
+- single project for everything
+- a project per release
+- a project per component/module (ie. close to the repo layout)
+
+How do we want to structure this?
+
+I would start with a single project to not fragment this too much, as w=
+e have=20
+a relatively small team actually looking into this, so everyone is look=
+ing at=20
+most sub-projects anyway. And should we eventually hit scaling limits, =
+we can=20
+always expand this I think.
+
+We of course should also talk about what we actually want to put in the=
+re. My=20
+current motivation is having a place to collect the tasks for getting m=
+ore of=20
+the former pimlibs into KF5, and anything else I run into on the way th=
+ere=20
+that we eventually should clean up/improve.
+
+regards,
+Volker

+hi..
+
+i noticed a new branch when i pulled kde-workspace today (finally!): 
+activities_optional
+
+the lone commit in it was pushed on april 1, so maybe it's an april fools 
+joke, but if it isn't, it looks like someone is trying to do something that 
+makes no sense (and has no chance of being merged into master). so if this is 
+a "for reals" branch, perhaps the motivation behind it can be shared?

+hi..
+
+i noticed a new branch when i pulled kde-workspace today (finally!): 
+activities_optional
+
+the lone commit in it was pushed on april 1, so maybe it's an april fools 
+joke, but if it isn't, it looks like someone is trying to do something that 
+makes no sense (and has no chance of being merged into master). so if this is 
+a "for reals" branch, perhaps the motivation behind it can be shared?
