Contribute CS3 Recipient (Names) List

Question

When sending a Contribute (CS3) draft to other users, how
does the selection list of users get populated?
We have created Contribute users (/roles) and provided them
keys. They are successfully logged into Contribute , but their
names to not appear on the pick-list for routing drafts. What data
is used to populate the draft send-to pick-list? Is it derived from
a file on the web server combined with some other criteria?
The directory _mm\\ct3beta\WIPMetaData contains users' email
addressing structure, but nowhere are their equivalent first/last
names cataloged. Similarly from the Contribute Site Administrator
account, there is no apparemt way to change what users have entered
for their names.
_mm\\ct3beta\WIPMetaData

Answer 1

By reason of deduction, the list of users appears to be
populated from directory:
webroot\_mm\ct3beta\messaging\users\list
Randomly named XML files in this directory all have file name
extension
csi. These files contain the element
user_full_name. This element's value correlates to the name
presented in the list. By renaming the XML file's extension to
something other than
csi causes the name value disappear from Contribute's list
of the available names to pick from.
Why can't Adobe's documentation simply provide the explanation
of this relationship!!!
