Notes from previous meetings:
AMB - 2025-07-09 01:31:09
I jumped on the July 8 call at 8pm Central time and waited for a half hour, but there was no moderator to let me in. Are these calls still on-going?
stevel - 2025-07-09 07:13:16
Yes, although I can't always be there at the moment. There is no moderator per se - anyone can be the first admitted if you are logged in via Google or GitHub as per the Jitsi Log-in page.
