I think I'd like to see a "Users Opinions" forum.
For example, I could start a thread called "Omni 4000 impressions", and then write down what I think of the brush. Then other Omni 4000 users could also add to the thread (It would work best if only people with that particular brush contributed to that particular thread, but my guess is that can't be controlled)
The thread itself would float, but there would be a quick link to it in the "Users Opinion" forum (much like how the group builds work right now)
When somebody is looking for an airbrush, they get directed to that area or thread, where they can get thorough list of users reviews.
Obviously, doing this for every model kit is out of the question. But the common items... airbrushes, compressors, hoods, PE folding tools, brands of glue, brands of paint, I think it could help.
Am I making any sense? What do you think?
