{agenda} TTWG Meeting 31/7/2014

This meeting is scheduled for up to 120m. Please be ready for a prompt start at 10:03am Boston time.

We will have a short break after 57 minutes due to being human beings and having a limited ability to concentrate for a long stretch without needing a brief change of scene, extra coffee, biscuits etc.

Our teleconference is scheduled with reference to Boston Time, the correct time of this teleconference in your locale may change.

Agenda+ Change Proposals – progress and review

Change Proposal Index is at [5]. Priorities have yet to be assigned by Glenn and Mike (see actions above).

Change Proposal 2 [6] is now CLOSED-IMPLEMENTED.

Timeline updated in 13th Mar meeting. This isn't looking very realistic right now:
January-March: Clean up and complete CPs
April-July: Draft, iterate and edit solutions to CP issues <-- We're still here!
August: Last Call
