I guess so, but I hope all members will remember to write down the new review on the log book, with a link. We'll still miss reviews by new members who are unaware of all these rules, but I guess it will make it a little easier.
But what I do is: any time a thread is highlighted in bold meaning that there are unread messages, I scroll up as well to see if there is anything new above the last message. I think this fixes the problem, but a log book might help as long as everybody adheres to it. Otherwise it will just be another thing to click on, which for me is the main downside of the sub-forum = too many things to click on, and less foot traffic.
Maybe the log book should be a sticky in the regular forum, to improve the problem of less foot traffic in the subforum.
