Since the shopping site update you can only see your reviews by searching for them on the product page, there is no automatic way of seeing them all together because the live reviews no longer have individual links like they did previously. This is a huge annoyance when it worked so well on the previous site!
This is why some of us post in the My Reviews thread. You can then create your own short cut that takes you to just your reviews. For example, this is the link to mine. You see the thread OP and then just your own reviews all listed together. It also means when talking about a product on the forum you can directly link to your review of it which is helpful.
