irc #planning Log From This Meeting

11:06 overholt: clouserw, maybe it'd be neat to have a marketplace update every once in a while at this meeting
11:10 dveditz: cpeterson: jedp isn't here anymore... maybe take the Identity section out of the template or find a new owner?
11:11 cpeterson: dveditz: thanks. do you have a owner in mind? :)
11:12 dveditz: no, I don't know what's up there these days
11:12 dveditz: maybe replace Identity with FxA?
