Fill out the spreadsheet to let the group know what you are planning to teach in this meeting, and put your name on the "I'm interested in learning this" column if you see something you want to learn.
A big challenge for this group is to match people with the right skill sets. We will have 20-30 mins for you to talk to each other and figure out the right person to pair with. But keep in mind, with 30+ people, it can sometimes get a little overwhelming to try and find the right pair.
For this reason, I created a spreadsheet to pair up members before the meeting.
