Getting a lot of this question, both in irc and mail:

Why do I get 'Too many users in your class, please try again later.' when I try
to connection to ftp.mn-linux.org?

As stated in the .msg when you first log in:

 **WARNING** If I cannot reverse name lookup your host you are going to get 
 dumped into the default class which only allow 1 user. This mirror is for the 
 US and we are restricting it to US domains.
