　　欢迎你在%date %time 访问我们的服务器, 你是第 %unow 个用户，最大用户数为 %maxusers，在上24小时以来，共有 %u24h个朋友访问这里。

　　注意，CLIENT端每行只显示80个字符，而返回码就占了4个字符。所以，建议定义信息每行最多70个字符。

建议：自建FTP的朋友，建议多使用下面的符号：
　　%Disk - 用户当前磁盘驱动器
　　%DFree - 用户当前剩余空间（KB）
　　%QuotaMax - 最大可用磁盘空间（KB）

　　以便给上传的朋友知道现在的空间可用情况 。

　　当然可以设置限额：
　　Menu--〉setup---〉users...----〉Quota: Enable disk quota: Maximum: XXXMB
　　这样可以用
　　%QuotaUsed - 已使用多小配额空间（KB）
　　%QuotaLeft - 还有多小配额空间可以用(kb)
　　%QuotaMax - 设定的配额

　　建议是在登入信息和目录改变信息里加入这些宏，这样使用FTP人会方便很多。

　　The file upload and download message directives are for the current session only (i.e. they do not show the aggregate over multiple sessions).

　　The '%ServerDays', '%ServerHours', '%ServerMins', and '%ServerSecs' directives are meant for use together. The number of hours is what's left after the number of days is subtracted, and the same goes for the number of minutes and seconds.

　　Example Message

　　Please keep in mind that the average client has only 80 characters per line, and the first four are taken up by the reply code. Please be brief, 70 characters should generally be considered a safe maximum.
