Re: [admin] Agenda - teleconference 15 April 2015

Hi TB,

I guess your question is about the last POST?

It seems to me like that should be two separate annotations. One noting
that it's spring, and the other noting that where it was taken, as there's
no way to link individual bodies with individual targets.  Otherwise,
according to the spec at the moment, each body is about each target.
