Would be great to allow admins to store multiple templates for new user welcome emails.
e.g.
----------------------------
Dear %firstname %lastname%,
your account has been created. Your login details are:
https://my.omniture.com
company: %company%
user: %username%
initial password: %password%
Please find additional resources here:
http://intranet/omniture/
----------------------------
Allow to specify a senders email address, so the new user can just hit reply.
This would save much time for admins.
