How to cancel your Obsidian Portal Ascendant Membership?
The Obsidian Portal Ascendant Memberships automatically renew every 1 month, 6 months, or 1 year depending on the membership that you chose.
Your Ascendant Membership can be canceled by visiting your profile, then clicking the "Membership" tab, then clicking the link "Downgrade back to the free account". This will display a confirmation dialog that will ask you to confirm that you wish to roll back to a free basic account. To roll back your account to a basic account, click "Yes, downgrade me to free".
