We manage the Workbench Reviews in-house with a crew of mostly local reviewers. There are a couple of places on the site where you can and we encourage you to post your own comments and reviews. First, if there is a kit we've reviewed, it will be on the website and there is a place for comments about the kit. We really encourage folks who've built the model to add there comments and suggestions. The Forum itself is a great place to post review type builds. Just put it in the appropriate section with a header that tells people which kit it is and go from there.
Welcome to the FSM community!
Cheers, Aaron
