The guys that are working on the phpReview Project are looking for developers to help them work on some of the portions that they just don't have the time for. Wonder what phpReview is? "phpReview is aiming to be a complete Open Source reviewing system, entirely based on PHP. It will be redesigned to be a general reviewing system, including voting, reactions and about everything else found in a good reviewing system." They are also looking for people to give them reviews of books (English) too so that they can start generating a base of data. So, even if you're new to PHP and don't feel like you can help out all that much, you can! Review your favorite book at their site!
