Ernesdo, (zyhrllos), is a moderately active user, and has been a part of the community since 2013.
He only seldom makes levels, and rates much more often.
He discovered SMF in early 2012, although didn't sign up for Pouetpu-games until 2013. He was then active before quitting in 2015 due to the inactivity of the site, including a lack of updates and care from the site owner, and any site moderation.
In 2016, he came back only to find PG abandoned by the community, but luckily found LP through various profiles advertising it, and has been active ever since.
Ernesdo also used to be part of the Super Mario Construct developer team, but has since left the project.
