-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Side-topic (and subject changed), but do we have centbot running in this channel? I'd love to get us in the habit of using Meetbot, it makes for such nice meeting minutes and logs. Can I offer to join all meetings happening for the next little while and run the bot to show how the flow works? (I can also moderate any IRC meeting that folks want, so all of you can be participants; it can be hard to moderate IRC and also discuss.) Anyone who wants that help etc. you can invite me to your meeting, karstenwade@xxxxxxxxx is my calendar.
