I've written a custom Register page to facilitate capturing and storing of custom data for our web site registration.  I couldn't just use the customization features from Manage Profile Properties as the data is shared with other non-web applications and is replicated around the world.  Therefore it is stored in a legacy, corporate, non-DNN database.

Now all that works just fine for user registration, but I need to customize the administrator User Accounts management so it can also apply adds/deletes/changes) to my corporate database.  Outside of recreating the whole User Accounts management module (which I obviously don't really want to do), is there an easy way to achieve this - perhaps via the data providers which offer some form of extensibility????  Any help would be most appreciated.
