Just a fellow editor here.
Since Portal is the best video game series ever. I decided to come here and see what I can do. I was going to edit anonymously because I don't like to waste my time creating an account on foreign websites but since here they require me to create an account, but whatever.
For the second one, I right clicked on the logo of this wiki and selected search by image and that's what I got. It thinks it is the Portal 2 logo, lol
