I am intrested in buying a license of this great plugin, but I have one question before.
Can I use Gravity Forms to read a user id from an url?
To keep it more clear, I would like to explain the problem for which I need a solution.
Some friends of mine like to send a newsletter to their costumers. If those customers are coming to my page they would come there with a special tracking code (something like http://www.domain.tl/?ref=xyz). I would like to track now this id and if they fill out the form, I would like to prepopulate a hidden form field with this id.
Can Gravity Forms do this for me?
Thank you for your help.
