Actually I did approach him and I also wanted to do JoS activism, and I still want to do.
But the thing is I don't understand the app you use to communicate. I can't really navigate the function. When he first posted on the forum about activism I was so excited and I even told him I'll do my best. And then I installed the app and don't understand anything. I even joined the server there but also couldn't understand anything and how it works. It's not in any way the fault of the guardians or JoS. Its my fault that I couldn't understand. I tried several days to read the chats in the server, but still couldn't understand anything what to do. So I became really embarrassed and ashamed because of my incompatibly and deleted the app. I further did not contact anyone about it because I was so ashamed and didn't want to waste anyone's time. And I completely understand that it's not the fault of JoS in any way, it's my problem.
But I'm still open to work for JoS. But I'm too embarrassed and don't know what to do and I don't know if I have the right to approach him about this anymore.
