When I signed up for the site and look up in the part were the review button was suppose to be it wasn't there as indicated by this screen shot here.
This seems kind of weird considering the fact that I signed up for a few private beta site before and there is all ways a review button as soon as I sign in. (because of automatically getting the close privilege.)
Please note the reviews are still accessible via the link: https://bioinformatics.stackexchange.com/review
If this is just a status by design feature and not a bug sorry for the misunderstanding.
