Let's say I just have one identity in a User Account. Then, I make another
User Account.

Anyone know if it's possible to make adjustment (to the registry, probably)
so that when I open the Identity in the newly-created Windows User Account,
OE relies on the same registry settings as in the original User Account.

So, no matter how many User Accounts I make, there is only one registry ever
being used by OE.

That means if I make a message rules change, or Account change in OE, when
in any User Account, these changes are reflected in all the User Accounts
when I open OE. Thanks.
