Compu-Global-Hyper-Mega-Net is CursedSilicon's "retro Internet" project, consisting largely of Windows XP era services.
Symlink is connected to the CGHMN and currently has the following services:
cisco). Poke around IOS 12.x, or telnet to other CGHMN or dn42 hosts, or pad to public Telebahn hosts via X.25-over-TCP.
There is a web interface available, but the primary interface to FirstClass is through the native desktop client (available for Windows/OSX/Linux). To register, either fill in the web form, or use the desktop client and log in as your desired username and password. Don't forget to input the server address under "Advanced".
FirstClass is set up for SMTP email, but newly registered users aren't automatically added to the CGHMN group, and won't be able to receive mail at the correct domain (contact me to do it manually).
Services that might be available in the future: Lotus Notes/Domino; Windows 2000 Terminal Server.
