New Reviewing System
I wouldn't put this suggestion at the top of your list, but I think it would be good to have change in the reviewing system on the main site. It can get quite annoying if you're giving an in-depth review, and you have to write the tag things in every few seconds (<p></p><i></i> etc.). Even if it was changed to a style like what we have here on the forums (you are able to highlight some text, click a button, and then it's in italics) it would be much easier.
Also, would it be possible to make an option for editing your reviews? I'm a major perfectionist, and in the past I've actually deleted whole reviews because of one silly mistake.
I think this would save a lot of time, and probably encourage more people to give long, constructive reviews.
