I found the website bookgeeks from the Reading Room discussions, and found that they were/are looking for book reviewers! If you've written any book reviews, they might be worth a look. I get to pick out new books, they have the publisher send them to me, and I read 'em and review 'em! And keep them! Pretty sweet deal. I've done a few already, and I'm currently reading "Born Wild" by Tony Fitzjohn, his biography about living in Africa and working with George Adamson (of Born Free) and his lions. I'm dying to go to Africa now!
Heads up for anyone on the fiance visa, or anything else that doesn't allow paid or unpaid work: I don't know how fussy the BA might be about it being unpaid work, or if getting to keep the books might constitute a form of payment, so I guess just be wary.
