+
+It's almost time for <a href="https://www.meetup.com/atlantabitdevs/">Bitcoin Socratic Seminar #48</a>!
+
+## What is a Socratic Seminar?
+
+Inspired by other BitDevs meetups around the US, our Socratic Seminar events are formatted to foster debate, information sharing and lively discussion.
+
+1. Discussion topics are provided ahead of the event
+2. The event moderator(s) leads the audience through the topics
+3. Raise your hand to grab the mic and participate in the conversation
+4. We go to a bar afterwards
+
+## Logistics for Tonight
+
+Tonight we'll be meeting at ATL BitLab. Join our <a href="https://atlantabitdevs.org/telegram/" target="_blank">telegram channel</a> in case you need to ask for help finding us the night of the event.
