Re: Review edit?

Hey I've written my first review ever (and only because I ranted too much to put that into a comment really) and well I've sent it and went to make myself some tea. During that time I came up with at least 3 different ways to improve that review, so I've searched for an option to edit the review, but I couldn't find such option. Does it exists or do I need to scrap the whole review and post it again?
