Well you can always use the
ScaleWiki Review Section.
I was talking with Jay about changing the Review thread by a Wiki long time ago. It was the main idea of ScaleWiki and he was quite happy with the idea, but the collaboration never gone further (some PM problem and time by Jay or something, I don't know)
We all agree the Review Thread is badly organised and hard to navigate. (there was a thread this spring about that, and this is what gives the idea of a separate place for that) Also, I don't think many people is looking at them because it just take so much time to find what you are looking for (have to browse the 4 pages (it could be worst) to see if the kit you are looking for is there. In other hand, a new forum only for that wouldn't a great idea. I don't think there is enough interest to give life to a new section. (there is only 7 review in the last year in this thread)
Anyway, the more information we have, the better this place is. If you want to post review of new tools, detail set or what ever related to modeling, then I don't see why it would be bad.
