Email fillable form without having to save

Question

Hi,
I am using Acrobat Pro 9 to create a fillable form and the users of this form will have Acrobat Reader 9 or earlier.
Is there a way to email a completed, fillable pdf so the recipient of the email will receive the completed form but the sender does not have to save the form prior to sending? 
I've created this fillable form on a shared network drive for our staff to complete when they want to request time off from work.  In order to avoid using paper, I want them to fill out this form electronically and email it to their supervisor but I don't want them to be able to save the filled out form.     I tested the form and when I fill it out and send it to myself, it comes back as blank...unless I save a copy of it which I don't want to do.
Any comments would be appreciated.
Thanks!

Answer 1

Thanks for the response Bill.  The form was created using Acrobat Pro 9.
I understand the concept of having to save the form but not the data however most of my staff are not very computer literate and I need to keep it as simple as possible:  
1. Open the form, fill it out and hit Send.
2. Recipient opens the email, clicks the attachment and reads the form. 
I don't mind setting things up and doing the hard work but if the users have to do anything other than 1 and 2, then its not worth setting up.
I guess the main issue with staff keeping a copy of the form is that they can then go back, change something on the form (ie, the date they want time off from work) and then resend the form.  Sounds childish but you don't know the people I work with.  lol
Maybe I should ask:  is there a way to automatically generate a date stamp on a document once it is saved and it can't be deleted or altered?  If a completed form is sent to the supervisor and the date stamp is before the current date, the supervisor will know that the form was altered.
Thanks,
