When messages are imported into the data base at each 
 netcall, the user names are read. OpenXP can put      
 previously unknown names into your user list          
 automatically, and this setting decides which ones.   
                                                       
 Note: persons to whom you send a PM are also          
 automatically put in the list.                        
                                                       
 All     Puts all users in the user list.              
             (Use with care)                           
                                                       
 Z-Netz  Puts only users whose addresses contain       
         no ":" or "%" signs into the user list.       
         That stops users which have come over gates   
         from other nets being registered.             
                                                       
 PMs     Puts only Users who send you a PM into        
         your user list.                               
                                                       
 Except under special conditions, PM's is the only     
 sensible setting. Otherwise over time you get simply  
 thousands of users in your list, 99% of whom you      
 never have any cause to address. Persons you send     
 messages to are put in anyway.                        
                                                       
 You can put any user specially into your list while   
 looking at their message in the message window, with  
 Ctrl-U.
