...since the second review was approved and posted? I don't really know why yours hasn't been activated but if it's been less than 24 hours I wouldn't be concerned. It seems to me it took a little time for my initial VIP membership to be activated once my 2nd review was approved and posted. If it hasn't been activated by 36 to 48 hours use the "Contact Us" link at the bottom of any page and ask.

at least for the first membership. After that, they will add 15 days for every review. No freebies here

You will see why it is unapproved. It could be you did not put the website link in exactly how it should be, or that you did not have enough details. You can submit the same reviews over until they are approved, from what guys have told me. A few times their reviews lacked juicy details they felt were tacky,and they told me as such, but did not want to add anymore. You can't make TER cater to how you want to write a review. Just ask them is all I can advise.
