Please can you fill in these fields and click subscribe. A new page will open and you will see the possibility to leave a reply/comment and down that box you have 3 fields, name, email and website. It is in the website box that you will copy the URL of your WordPress, because that is the website and then click on post comment. You will see a text that the comment is waiting for approval, but don’t worry, this means that it is pending in my blog.
I am using a subscription form but do not worry is just the way I have found to do this 🙂
