    EXPECT is another shell for linux terminal, than not many people know  
    about. with it you can write scripts to automate tasks, like  
    connecting to other machines via ssh/telnet. we could also use it to  
    automate tasks in our bbs machines, from within the bbs it self. 
     
    below is such a script that connects to Another Droid BBS, selects the  
    ascii theme, cause EXPECT dosn't go well with ansi, logs into the bbs  
    (i know the theme is fucked up :| ), goes to the message area, selects  
    the fsxnet group, joins the first area and starts reading the new  
    messages. 
     
    copy/paste it, make it executable and use it like: 
     
    ./scriptname <username> <password> 
     
    EXPECT has some advanced commands, but even with the simple ones,  
    someone could do cool stuff. if you have the patience you could write  
    a script that could auto-validate the last user who registered in your  
    bbs, log in and do a mass upload to the file area or do a globar text  
    search in the messages area for a specific text (lurker! :) ) 
    you could also use it, out side the bbs, to log in a ssh shell and do  
    other stuff etc. 
     
    if you make something, don't hesitate to share...
