You should be able to see a new forum up top, "Star Wars":viewforum.php?f=34
which has a topic for each star wars set in the set guide. You can now rate sets and add mini reviews. latest 5 comments will show up on the set's entry in the guide. the ratings will show up as well. one caveat about that is that the entries are cached pages, so comments and ratings may not show up right away, but they will eventually as time passes and the cache cleans itself out.
comments are moderated on that particular board, so please follow the format if you want your comment/mini review to be approved. thanks!
if anything's broken or need fixing, please let me know.
