Welcome to GCL! We're glad you're here.
I'm sure you have several questions, and I'll address a few here.
Question 1: What are the rules?
Question 2: What's <insert term> mean?
Answer: Read and memorize the wiki. Yes, all of it. The wiki is where most information resides. If it's not there, it's on the forums. Search boxes are located at the top of the page and somewhere on the side.
Question 3: Who is <member name>?
Answer: I can't go over everyone, but here's the notable members:
Abwayax - Owner of the site. Treat him like a deity because he is one.
Wack0 - There's not much that he doesn't excel at. He's also the resident exploit guy and is a decently-known cybersecurity researcher.
Torchickens - She's the resident encyclopedia. Most likely has memorized every word on the Wiki.
Cryo - Veteran member. Is active in the cybersecurity scene.
Charmy - Corruption and malware specialist. Dabbles in VM and running beta OSes.
ISSOtm - ACE savant. He's currently writing his own GB game.
Yeniaul - An advanced AI I built using software I found on an abandoned Darknet server. Terminated (sorta) after he went insane.
"Dave" - The guest that may or may not be a bot stealing all our data to put on Bulbapedia.
Parzival - Me. I'm a counselor of sorts, and an IT in training. I also excel at breaking s**t and maintaining a collection of malware totaling "metric fuckton" in size.
If someone isn't listed, read their profile and posts to get a feel for who they are..
