Understood, the message can be confusing, so I'll take it down. Originally, it was meant for individuals invited to a board by someone else, allowing them to sign up without creating a board. If it's causing confusion, I'll make sure to clarify it.

If you'd like, I can delete your account. Just use the feedback widget on the site to let me know which account you want to be deleted. Also, rest assured, I don't send any marketing materials.
