Hi I´m trying to create new users on @api/deki/users

I followed the code pubished on the FAQS How do I...Use VBA to export data to MindTouch?:

http://developer.mindtouch.com/Deki/...o_MIndTouch%3f

under Post: Funcions.txt:

http://developer.mindtouch.com/@api/..._Functions.txt

Following this code I've reploaced:
xmlreq32.Open "POST", "http://" & myServer & "/@api/deki/pages/=" & mypath & mypage & "/contents/?dream.in.verb=POST", False

with
xmlreq32.Open "POST", "http://" & myServer # "/@api/deki/users/=" & "UsuarioPrueba" & "/contents/?dream.in.verb=POST", False);

and where the code says

xmlreq32.send(pagetext)

pagetext contains:
<user><username>UsuarioPrueba/username><fullname>UsuarioDePrueba</fullname><email>UsuarioPrueba@somewhere.com</email><permissions.user><role>viewer</role></permissions.user></user>

The resut is a status 404 Not Found

Please sombody can help me with this
