I think it would be helpful to be able to edit the product posts, as well as the reviews if you are the poster. It would also be nice to have a separate list for products that have been reviewed, as opposed to searching through the whole list and finding a bunch that haven't been that you would like to hear opinions about.

I don't know if it's possible to do what I suggest, but it seems it would be helpful.

And something I noticed in the reviews: Some of the reviews, as well as product descriptions, are cut off half way through them. Maybe a character limit could be shown beside the entry box that counts down while you type and doesn't allow you to type past the limit?

I hope you like my suggestions! :)
