Got a response (I told you Low priority works! 
):
Thank you for contacting SAP Active Global Support.
I am so sorry but when an Admin creates new users, emails are not sent
by the system.
After the users are created, it is up to the Admin to go to the Users
page and inform the new user of their S-User ID and Initial Password.
Users only get a system generated email if they go create their own user.
This process does not seem to make any sense... What difference does it make who creates S-user? You have the user emails in the profile, so just send them an email. Why does someone have to do this manually? At least send email to the Admin then.
So I'm in the US and the whole bunch of people in Europe have to wait when I wake up and remember to go to the SCN web site (among 1000 other things to do), then I have to find their emails and send them their logins.
Wow, this is some cutting edge technology running simple, just wow...
