I started with ProFTPd, did a quick dabble with WS-FTP then pretty quickly jumped ship over to pure-ftpd. Lean, mean FTP in its purest form -- secure but lots of features. So I was glad to see it included with CWP as a bullet point, but as states I don't use FTP anymore (and have FTP running on an alternate port on only one server -- the better to avoid script kiddie scans).
