I have a custom editform.aspx where I actually stay on the page after a save action but I need to show a message that states that the record has been saved. is this possible?
This isn't exactly what you asked for, but you could use Sharepoint Designer to send an email to the 'created by' person.
I don't know if you've used Designer already, but it is for free and can be downloaded here is a link for Designer 2013 (I use this, since I am using Sharepoint 2013).
If you need me to post a screenshot of how the code looks in Designer, let me know.
