Re: search. So, the problem here, such as it is, is that the search bar you're seeing in the header, the one that comes up if you click the magnifying glass? That's not a full site search. That's just a forum search, and by default it searches thread titles. I'd like to change that at some point because it does lead to the occasional (reasonable) misunderstanding.
That said, there is a Review-specific search that works very well. Just hit
Reviews, linked in either the header or footer of all pages, and scroll down and look to the left. From there you can search by film, reviewer, and rating:
You can also go to your own profile (click on your avatar where the notifications come up and hit View My Profile), and on your profile you'll see a
Reviews tab that lists them.
As noted by Takoma, this assumes the reviews have been tagged. Let me know if you're just looking for things you've written but which haven't been submitted/accepted as reviews, since that'd be a bit different.
