WHO <#channel|user>

The WHO command displays information about a user, 
such as their GECOS information, their user@host, 
whether they are an IRC operator or not, etc.  A
sample WHO result from a command issued like

The first field indicates the last channel the user
has joined.  The second is the user's nickname.  
The third field describes the status information about

G       -       The user is set away.
*       -       The user is an IRC operator.
@       -       The user is a channel op in the channel listed
                in the first field.
+       -       The user is voiced in the channel listed.

The next field contains the username@host of the user.  
The final field displays the number of server hops and 
the user's GECOS information.

This command may be executed on a channel, such as
"WHO #lamers"  The output will consist of WHO 
listings for each user on the channel.
