I have a suggestion, it would be beneficial to remove the hyperlinks in the email address tab, or at least make it so that you can right-click so you can copy and paste the email address into your own email program.  The option to make all email addresses have to be globally changed to the category of "other" isn't a very clean solution.  To have to explain to everyone using your system why the email address tab is blank and that email addresses have to be found under the "other" tab isn't very efficient.
