Primary DOOM FTP Sites and Mirrors
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The "Primary" site contains the "master copy" of the DOOM FTP Archive.
Contributions can be uploaded to the /pub/idgames/incoming directory,
but LMPs should be uploaded to the /pub/idgames/lmps/incoming directory.
"Mirror" sites each have a duplicate of the primary's idgames hierarchy
(sometimes with a different name) that is updated on a daily basis.
If a mirror site is closer to you, please use it instead of the primary.
Log in as "anonymous" or "ftp". Use your e-mail address as the password.

NOTE: World Wide Web surfers can use http://www.cdrom.com to browse the
/pub/idgames directories. Unfortunately, file HREFs use ftp:, so
copy, paste, and edit the link to use http: for faster access. :)
SPECIAL NOTE: John Van Essen (that's me!) created a WWW page showing the
www.gamers.org/pub/games/idgames hierarchy in a graphical directory
tree format with hyperlinks to each directory at www.gamers.org.
http://www.gamers.org/ftp/ftptree.html has full tree.
http://www.gamers.org/ftp/ftpbush.html has fewer subdirs.
