We made our first call for petitions (now called campaigns) on May 27, 2017, seeking Avi-related content to add to the book for PTX and the book especially for Avi. Kathy (@McKathlin), our founder, made a nomination:
Once the nomination reached 10 likes, we moved to asking permission from Kato, which they publicly granted.
So we launched the petition. It passed the required 100 likes in only 14 hours.
