Assuming yes, gave you action 15:25:11 will try, thx 15:25:25 thank you dom, thanks Andrey 15:26:06 fjh: will revisit on our next call, 12 Jan, merge before if ok 15:26:29 fjh: Next call is 12 Jan 15:27:14 fjh: Merry Christmas, happy holidays and Happy New Year to all! 15:27:18 Topic: Adjourn 15:27:24 rrsagent, generate minutes 15:27:24 I have made the request to generate http://www.w3.org/2016/12/15-dap-minutes.html fjh 15:29:11 wanming has left #dap 16:22:03 Andrey_Logvinov has joined #dap 16:23:21 s/.../.../g 16:23:27 rrsagent, generate minutes 16:23:27 I have made the request to generate http://www.w3.org/2016/12/15-dap-minutes.html fjh 17:29:07 Zakim has left #dap 17:49:54 mats has joined #dap
