No worries! Ask until everything is clear. For C-1, your own stack that you're starting up, you have to write a phrase and send it to Psychotic labelled C-1. No drawing involved here, Psychotic is supposed to draw the piece of text you send him.
You are always going to send PM's to Psychotic, nobody else. If you receive a drawing from Agent Proto, send a text to Psychotic describing what you see. If you receive a piece of text from Agent Proto, make that piece of text into a drawing and send it to Psychotic. Hopefully that clears things up!
