Since you're already advertising in your signature, there are two things you can do:
1. Offer to review people in chat and direct them to your thread.
2. Go out and review lots. It's not as obvious now, with how it isn't as easy to for people to see they've gotten a review, but the more you review, the more people see that you're a good reviewer and will want to ask for your reviews.
Once Notifications are up an running though, and if you've been reviewing, the requests should come rolling in. ;P
What really knocks me out is a book that, when you're all done reading it, you wish the author that wrote it was a terrific friend of yours and you could call him up on the phone whenever you felt like it. That doesn't happen much, though. — J.D. Salinger, The Catcher in the Rye
