Inquiring how to edit or delete old reviews I wrote.  What are the steps?  Do you need a VIP membership to edit or delete?

You have 1 review. I don't think you can remove or edit anything by yourself at this time. You can use "Contact Us" (at the bottom of every page) and explain to Admin what you want to do and ask them to do it for you.

When you submitted to review to TER it became TERs property so you don't have any further say -- unless of course you submitted a fake review (session never happened) and want to now correct that error in judgement. Then they might.
