Put this in act_wiz.c

void announce( CHAR_DATA *ch, char *argument )  
{
    DESCRIPTOR_DATA *d;
     
    if ( argument[0] == '\0' )
    {
        send_to_char( "announce what?\n\r", ch );
        return;
    }
    
    for ( d = descriptor_list; d; d = d->next )
    {
        if ( d->connected == CON_PLAYING )
        {
         send_to_char( "{BAnnouncement:{x",d->character);
            send_to_char( argument, d->character );
            send_to_char( "\n\r",   d->character );
        }
    }
         
    return;
}

Then just put something to the angle of  sprintf( buf, "{B%s has wandered into DWB -=[%d]=-{x", ch->name,ch->level);
        announce( ch, buf );
 
Or whatever you want it to look like in the file
