extending meeting posts for development meetings
Decide a special, different name for development meetings for us to look for on our public Google calendar, and then post reminders about development meetings after our Wednesday meeting, and the day of development meetings.
Post an @here message to #general that we are having a development meeting on Thursdays, the day after our normal meeting. Come up with a couple of ways to say, 'couldn't make it yesterday, or want to learn more? come to our development meeting this Sunday at [meeting time] in [meeting place]' as indicated on Google Calendar, and shuffle to humanize the post.
Then, the morning of the meeting, at Sunday at 10am (provided our meeting are on Sundays at 12:30-4:30) post another reminder that we're holding our development meeting later today, note its location and time, and that we hope to see anyone interested there and to stop by at any time. Again, use only @here and not @everyone. Include a number of ways to say this so the bot is 'less botty'.
