Pass extra parameters to the Idea board URL

As a developer

I would like to be able to send extra parameters in the Add new idea to the board link 

So that it will be easier to debug issues and have more information about the system used by the end user

Example:

if my ideas URL is addnewidea.com, I would like to pass the email address and the system info parameters in the URL. Final URL to submit a new idea will look like - addnewidea.com?email=test@email.com&system=thisinformaton. I would like to auto-populate the email field in the new idea form, so that the user doesn't have to type again, and I would like to have a hidden field for the system information, so that we can easily track data.
