WG meeting should be at 16:00 UTC (11:00 EST, 17:00 Brno, 11:00 Boston, 1:00+1d Tokyo, 2:00+1d Brisbane) in #centos-devel on Freenode.
By "on demand" I mean I don't have any agenda, but will be around on the #centos-devel during that time, just if anybody wants to discuss anything.. for example some specifics about git branches/repos and CBS tags naming I've sent to the mailing list.
