You’re logged into the www.remarpro.com support forums, which is completely unrelated to WordPress.com.
To clarify, WordPress.com and www.remarpro.com are two different entities. At WordPress.com, we provide hosting, support, and tons of features for blogs – including the features that Jetpack provides. Users also have the option to purchase a variety of upgrades to customize the look and feel of their blog.
www.remarpro.com is a software for self-hosted sites. With www.remarpro.com, users are provided access to all backend files and can upload custom themes and plugins – including installing Jetpack.

As I indicated in my first reply, you need a WordPress.com user account in order to connect Jetpack. Let me know if you need further clarification and I’ll be happy to answer any questions.
