[ic] accessing username and password in email receipt

[interchange-users@icdevgroup.org (Aaron Hazelton)]

I found quite a few messages on this in the archives, however
the solutions listed are not working and I cannot figure it out.

In particular, I found this post by Racke about grabbing the
username of an autocreated user:
http://www.icdevgroup.org/pipermail/interchange-users/2001-November/0148
40.html

but when I tried that in the email receipt, I get nothing.  I 
also tried the obvious in both an auto user and logged in
user - both get nothing:
[data session username]
[value mv_username]
[scratch mv_autocreate]

maybe im blind, but it seems like it should work ?

OR, should I just override the NoSearch, do a loop
on the userdb and use a [loop-data userdb username]
for this ? seems like that would work.

thanks,
Aaron
