If you want to add Pure Good to SCP-105 and SCP-131, you have to create a proposal blog and get an approving consensus first. To do that you have to create blog and read this tutorial to explain who you are nominating, and explain everything they have committed to qualify for the category. The proposal must have the layout shown in the aforementioned tutorial, and under each section you must write the matching information within each given section. The details for what needs to be added in each section can be found in the tutorial, there is also certain criteria that needs to be met in order to earn support.
Thank You, and I hope perhaps you’ll give it a try.
