Creating forum threads.

Also, I am not sure how/where to find the URL address required below.

To my understanding, you are referring to this: 

That is where you put the link of the website where your form is embedded if it is embedded. If it's not, you can place any other link that may help us determine your issue easily or quickly. Like, for example, the link of the form in question, so we will be able to know right away which form to check.

I hope this helps. Let us know if you need any further assistance. Thank you.
