This list is made by Anthony Jacques (anthonyj@jacquesa.freeserve.co.uk) and is based on the (official?) Atari ST FTP site list by Hallvard Tangeraas (hallvart@sn.no) with kind permission.
His list (which is updated roughly once a month) can be found at: ftp://ftp.sn.no/user/hallvart/atari/info/ftplist.txt
...or as the WWW version along with various filesearch-engines at: http://home.sn.no/~hallvart/pages/atari_ftp.html
Mirror sites contain the exact same directories and files, but have different entry points. Try to use the one closest to you geographically and not during business hours (in that geographic area).
In order to get information about how to do this, send an email to the various addresses below with the word: help in the mail itself. If possible, do not include any 'signature' in the mail, as the automated system which replies to these mails tries to interpret any message (and with a certain amount of errors no response to your requests will be given at all).
