Billing on my account...

...my account just renewed automatically, without even the courtesy of an email to inform me it was pending. I don't want to pay $40 for my membership anymore...the free subscription will be fine. How do I go about changing my membership and reversing the charges? (Didn't know where else to look/ask other than here. GS seems to be pretty good at hiding that whole process.)

The "Help" link at the bottom of the page. Click this, then click the link in the second question to cancel your subscription.

As far as charges being reversed, you'll need to contact Customer Support about that.

Thanks for the reply. I actually already found that link. My concern right now has more to do with wanting to change my account to the free one, rather than canceling it altogether and starting a new one. (I have some contributions, etc. associated with my account, and I'd lke to keep them up.)

Is that possible, or do I basically have to cancel the old account and set up a new one?

I believe you can keep it, but you really need to contact Customer Support.
