The following code creates folders off of a Work Flow call. I have removed some of the unusual code we use to check the current folders and align our names. There are a number of unimplemented but known improvements needed (better error processing – I drop some exceptions And I should send back the message properly to the user via WF - see the development kit)  That being noted this code will need an Active Directory ID with write access to your file stores.  Please contact me if you have any questions.  This is using the 1.1 asp.net framework.
