I'm still waiting for a "My Chester Zoo" or similar login from the front page (or at least easily accessible) to track memberships and adoptions, and although the password change feature at least now doesn't screw up the page so that you can't click on the fields, it still complains that my old password has been typed in wrongly so I can't change it from the "temporary" one I was assigned yonks ago when I first registered.
As for the rest, I find it messy and hard to navigate, plus with things like red birds of paradise still listed, it's not exactly being kept up to date. I'd like much more information about species kept, not just a select few. For example, there are only 3 passerines listed out of goodness knows how many, and one of those isn't even there anymore!
