I own a domain and hosting account that is hung on Godaddy. I have a 
sub domain that has to do with personal medical information. I 
created it because I live alone and if something were to happen all 
necessary information is on that sub domain index web page. I don't 
use passwords or encryption for this page because if I am brought in 
the ER somebody needs to look at my dog tag and use the address to 
bring up my info. It is the KISS principle. I use a robots.txt file 
on both the main and sub  domain to avoid searches, and the fact that 
somebody would have to know the sub domain address in-order to bring 
it up which is unlikely .... or that is my theory.  I think we have 
some web developers in the collective so please give me your 
thoughts.  There is always going to be a risk but is this good enough. Thanks w
