If you go to My TER and then look at the options under More you'll see a link to My Board Posts. That will list your posts and (for a limited amount of time, not sure if it's 20 minute or an hour or a day but not forever I'm sure) you can then Edit your post.  

No need to reply to your own post.

You might also want to check in the K-Girl forum. While that's largely LA based it does have a larger readership so someone might be able to suggest somewhere for you.

Also, searching the reviews (and perhaps agency profiles) should also provide some result with a minimal amount of effort.
