Forum news please read !
I'm not sure what you mean by posting twice. My understanding (and what I'm observing) is that gear reviews, which you can do just by adding them to the "Gear" tab in your profile (or just going to the product page), are now IN ADDITION automatically published to the most relevant forum (i.e. Sony A77 review here in Sony Alpha SLR/SLT Talk forum), not just on dpreview's Sony A77 product page.
In the previously mentioned link some took the "original poster" to task for his opinion; there was some suggestion of trolling. I suspect the OP has no idea his opinion (whether right or wrong) was being taken to task in the forum.
You used to just see these user reviews on the relevant product page, such as here.
