So I need to create a workflow rule and a field update when a user is created to store this date...and load this to all existing users...just to send an email.
It must be monday, or I need a lot more coffee.
Thanks!

Unfortunately you can't do this. I can't find any documentation from Salesforce on this, but there's an existing answer on success.salesforce.com:

It isn't available in the workflow formula editor either, so it looks like your only option is a regular field and a trigger to update the value whenever a record is created/updated.
