Mothercard (Em) Warden's registration name in SL was a silly mistake, due to insufficient knowledge in English more than 8 years ago. I won't go into any details... I could half cover it up by the display name Em Warden ( Em for "M" as in Mothercard).
The "Mothercard" has been a nuisance to me (and a riddle to others) during the years, and I finally got down to doing something about it. I created an identical twin avatar- and found that the name "Em Warden" was available for registration in SL! EmWarden Resident and Mothercard Warden have exchanged permits to edit each others objects, so the residents of CDS can occasionally see Mothercard rezzing things for Em. She is in fact EmWarden Resident's walking Inventory, or her private Archie, if you like 
Mothercard's parcels in the CDS have been transferred to Em Warden by two very kind EM:s, including all the objects in them. Em also inherited her e-mail address.
It doesn't matter whom of the Ms. Wardens you meet. They both look exactly the same, and they share the same typist behind the keyboard... But Mothercard won't be online much any more, so I suggest that those of you who have Em/Mothercard Warden on their friendslist say goodbye to her 
So- goodbye, Mothercard (Em) Warden, and hello Em Warden (EmWarden Resident)!
