How do I add a contact form to each of my multisite users?

I would like to add a contact form to each of my store users upon registration that automatically uses the new user's email address they used upon sign-up.

I installed the Contact Widget this does not seem to automatically use the new site user's email. I would have to change this manually, which I do not want to have to do, nor have the user do themselves.

Is there a way to configure this and/or another plugin that will do this for me?

Thanks for all your help.
