It really is super easy to cancel!
Just login to your account, click on the user icon in the upper right corner of the page, and in the dropdown menu click Settings. On the Settings page in the upper right part of the navigation links click Billing, then click Cancel, job done!
I am happy for folks to come and go as they please, and as needed for their professional and personal interests. Please know you can join back up anytime you like, and that your membership will remain active for the full month that you joined before it expires (or the full year, for annual subscribers). I am keen to make the site as useful to folks as possible, and I welcome your feedback on anything I could do better to make the site an ongoing value to you. I appreciate your interest!
