On creating a new user, I would like to send an attachment with email.
Unfortunately the FBA Pack doesn't support that directly - the code would have to be modified to support that.
I am unable to find the .cs pages in my live application, there is only 9 .aspx files on this C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\TEMPLATE\LAYOUTS\FBA\MANAGEMENT location, Please help its urgent.
You can download the full source code from the downloads page. After changing it you will have to recompile and package it, and then redeploy to SharePoint.
