Hi Musixland,
Thank you for your feedback.
You are correct, as of right now you need to sign-up for the platform in order to use the plugin. The WP plugin by itself is a supporting tool, rather than a stand alone landing page builder. The platform offers a free account that lets you create unlimited amount of landing pages without having to enter any billing information.
Our team is currently working on the ability to pass the login information from WP to Wishpond in order to eliminate the sign-up step.
I hope this help to clarify the situation and if you have any further questions please feel free to reach out to me here or by email: damir (at) wishpond.com
Cheers,
Damir
