Just noticed one thing in nopCommerce Project,
as we have a feature called "Product Review" by which customers can write reviews for all products.
But Product Review feature is available only for specific products, products which have specifications defined, only those products can have product review feature, and those which doesn't have any specifications defined, there is no way anyone can write product review for those products.
I guess it should be fixed and by default Product Review Tab should be available for all the product and if a product has got specification then 2nd tab for "Specs" should get activated.
(I hope this bug will be fixed in 1.6 version)
