Are you sure you are not related to that television series detective, 
Colombo?  You give me these little hints that send me screaming up the 
network path to find out more.  Ex:  "and my booklets, of course".  Now, 
'fess up, what booklets, where do I get them?  What do they cost?  I 
already know I am going to have to get them just because you know so 
much more than I do and I do not want you to think you are corresponding 
with a complete nit-wit!  Seriously, they sound like just what I need, 
tell me more.  I do have World of Iris and have gotten much of my 
information to date from there.
