I remember PK bitching about the group and Chilly in her annoyingbabybird blog. She said there were too many male characters, Chilly made stories about his 'fetishes', and that it ripped PMD-E off to a degree that made her rage. Basically being a total hypocrite lol.Her thing is PMDE. PMDU was the "successor" made from PMDE ex-pats ChillySundance, and a few other people who were once friends with PK. You can see the influence in a lot of its characters, art, and there was once a porn blog for it.

If i remember right, Sundance used to be in her inner circle for a long time until something happened but you can't say that she hasn't inspired people because PMDU is technically a spiritual (and better drawn) successor to PMDU. It also died horribly within the last 2 years.
Edit: pics aren't working but there's still a link.
