Query string from "Edit Product Full Description"

I have read almost all of the forum but could not find any posting that address posting information from the database in the product area.  

I would like to have a hyper link to "customize" a product the inludes the current users email address. The link will go to another website that will allow the customer to customize the product and the the customize image will be emailed backed to the customer.  

I can not find a way to to display the customer users email on the Full Description on the the Product pages.  

Thank you to anyone who can help!

actually a simpler question:
Is it possible to add variable such as current user email, store url, store email, and current user's full name to the product detail page.
