This is very important. I'm not sure if it's only premium members, but on RM, you can look up a reviewer's profile and see their other reviews. I like this because you can easily tell who is real and who is suspicious. People were recently asking about how to evaluate a new provider. Well, if they're reviewed by someone on RM with a bunch of reviews that are solid, that's as good - to me - as someone on here. And I did recently end up hiring someone despite their having one bad review out of three, because the client had given EVERYONE bad reviews.
