You've Discovered a Secret Level of the Internet!

Tired of the modern web? The endless scrolling, the targeted ads, the walled gardens? Ever wondered what the internet felt like before it was slick, corporate, and constantly watching you?

Welcome to SDF.ORG, the Super Dimensional Fortress. Think of it as a digital time capsule, a community-run playground, and your own personal corner of the internet, all rolled into one. It’s the internet, but like, the original version.

What in the World is SDF?

SDF is one of the oldest and largest non-profit public access UNIX systems on the planet. It's been running since 1987! That's before the World Wide Web was even a thing!

Forget fancy graphics and point-and-click interfaces. This is the command line. It's a text-based world where you have the power to create, communicate, and explore in a way that's totally unique and refreshingly simple. It’s a community of programmers, writers, artists, students, and curious minds who love the raw, unfiltered power of a real operating system.

The Loot! (Member Benefits)

So you get an account. What does that actually mean? You get a digital Swiss Army knife of awesome, old-school tools!

• 🚀 Your Own UNIX Shell Account

  This is your command center. From here, you can navigate the system, run programs, write code, and manage your files. It’s your home base in a vast digital world.

• 💌 A Seriously Cool Email Address

  Get your own @sdf.org email address. It's a badge of honor that tells the world you're not afraid to get your hands dirty with technology.

• 🌐 Build Your Own Retro Homestead

  Every member gets space to build their own website. But why stop there? You can also create a Gopherhole or a Finger plan. Party like it's 1993!

• 🤖 A Programmer's Playground

  Whether you're a pro or just learning, you get access to compilers and interpreters for languages like C, C++, Python, Perl, and more. It's the perfect place to practice your skills without any pressure.

• 💬 Connect Like It's 1992

  Jump into real-time chat with other members on IRC (Internet Relay Chat) or the local COMMODE. Post on the bboard (a classic bulletin board system). You can even use commands like talk and write to chat directly with other logged-in users.

• 🎲 Play Legendary Games

  Forget microtransactions. We've got nethack, rogue, zork, and a hoard of other classic text-based adventure games that will challenge your mind, not your wallet.

Okay, This is Awesome. What's the Catch? (The Cost)

Here’s the best part. SDF is run by volunteers and supported by its members. It's not about making a profit; it's about preserving a piece of internet history and fostering a community.

The "ARPA" Level: FREE!

• Cost: $0. Nada. Zilch.
• What you get: A basic shell account to get you started. You can explore the system, use many of the communication tools, and get a feel for the place. It's the perfect way to dip your toes in.

The "VPM" Lifetime Membership: A One-Time Donation

• Cost: A one-time donation of $36. (That's it. For life. No monthly fees, ever.)
• What you get: This is the real deal! You unlock a ton of extra features: your own webspace, the ability to run more processes, access to more software, and the warm fuzzy feeling of supporting a digital institution. A single payment grants you a permanent membership in the club.

There are other membership levels with even more features, but the Lifetime Membership is the most popular way to join the community and get the full SDF experience.

I'm In! How Do I Join the SDF Crew?

Joining is a rite of passage in itself. You don't fill out a web form. You connect directly.

Ready?

1. Open Your Terminal
   • On macOS or Linux: Just open the application named "Terminal".
   • On Windows 10/11: Open the Start Menu, type cmd or PowerShell, and press Enter. (Or, for a better experience, install the free PuTTY client).
2. Type the Magic Words

   In your terminal, type the following command and press Enter. This will connect you to SDF's new user creation system.

   ssh new@sdf.org

3. Follow the Yellow Brick Road

   You'll be greeted by a text-based menu. Just follow the on-screen instructions. It will ask you to choose a username (your "login"), a password, and a few other details. It's an adventure from the very first step!

That's it! Once you're done, you can log out and log back in with ssh yournewusername@sdf.org.
