HI Iratxe, Did you have any luck getting a 2nd class off the ground? I only have one person that I know in my class. I literally just set up a meet up and people began to sign up. I had 2 people I didn't know come to the first class, then 2 more, and 3 have stopped coming but 2 of them are consistent, making just 4 of us. I keep my class to one hour over the lunch break on Tuesdays, my group likes that because it keeps us on topic and doesn't take away from family time on nights and weekends. It was very intimidating setting up a class and having no idea if anyone would show up but they did and I figure that the ones that stay are the ones I am meant to connect with and learn with.
So, maybe just try setting up a class, with one other person you know and trust, and in a public place, and see who shows up. I printed off the Gnawal picture and walked around the restaurant and the people looking for it found it :) Let me know how try 2 goes. Feel free to google+ me and email me because I don't check this forum often. firstname.lastname@example.org :) thanks, Marsha
