This month's FTP site list is here again, this time with some changes. Re-distribution allowed as long as nothing is altered or omitted.
Mirror sites contain the exact same directories and files, but have different entry points.
Mail servers can be used to get hold of the same software as through FTP, but instead of using a lot of download time online, files can be 'ordered' via email. Re-distribution allowed as long as nothing is altered or omitted.
