I just did a workshop at a small non profit. There were 3 people who came there to meet me to chat about other non related opportunities and projects. We charged a small amount, 5$. It was not advertised or told (not by me or leaked through the topic of the workshop) that I would be there, nor am I famous. They came specifically for me, not the workshop (but did participate in a good way). Not sure what to take away from this, other than that it was really nice!
