 +[01] WHAT IS SDF?  (QUICK SUMMARY)
 +
 +  Welcome to the only all 64bit public access supercomputing center!
 +
 +  The Super Dimension Fortress is a networked community of free software
 +  authors, teachers, students, researchers, hobbyists,  enthusiasts and
 +  the blind.  It is operated as a federally recognised non-profit 501(c)7
 +  and is supported by its members.
 +
 +  Our mission is to provide remotely accessible computing facilities for
 +  the advancement of public education, cultural enrichment, scientific
 +  research and recreation.  Members can interact electronically with each
 +  other regardless of their location using passive or interactive forums.
 +  Further purposes include the recreational exchange of information
 +  concerning the Liberal and Fine Arts.
 +
 +  Members have access to games, email, usenet, chat, bboard, gopherspace,
 +  webspace, programming utilities, archivers, browsers, and more. The SDF
 +  community is made up of caring, highly skilled people who operate behind
 +  the scenes and in the underground to maintain a non-commercial INTERNET.
 +
 +  While we did initially start out on a single computer in 1987, the
 +  SDF is now a network of 8 64bit enterprise class servers running
 +  NetBSD realising a combined processing power of over 21.1 GFLOPS!
 +
 +  Our mass storage configuration is comprised of 60 spindles of mostly
 +  36.4gb and a few 9.1gb SCA LVD SCSI drives using DIGITAL Storage Works
 +  hotswap disk arrays.  We have roughly 2 terabytes of storage online.
 +
 +  We are networked via two sprintlink T1s and a T1 to savvis.  We do BGP
 +  peering and try out best to load balance between the links via a CISCO
 +  7xxx router/switch.  We are using a 'swamp' class C 192.94.73 which has
 +  basically been assigned to our site admin along with his class C back 
 +  when you could request one from the INTERNIC without much fuss.
 +
 +  The userbase is comprised of two major user groups:  USERS and ARPA
 +
 +  'user' accounts are free and offer many features.
 +  'arpa' accounts are permanent members and can vote on SDF features.
 +
 +  Supplemental ARPA privilidges include:
 +
 +    MetaARPA  ('trusted' member privs (cron, tcp port forwarding))
 +    TWEAK     (tweakable and additional disk quota)
 +    VPM       (Virtual POP3 mailboxes)
 +    DNS       (Domain Name Service)
 +    DBA       (MySQL database access)
 +    VHOST     (Virtual Web hosting - includes VPM, DNS and DBA)
 +    SERVER    (Server process (mud, nameserver, et cetera))
 +    MDNS      (Dynamic DNS)
 +    MLIST     (Mailing List service)
 +    DIALUP    (over 10,000 numbers in the USA + Canada)
 +
 +  Sponsorship information can be found on our website or in the FAQ.
