I always worry about feedback forms on sites; when you have a problem you fill them out and the system just eats them. You have no idea who they go to, whether someone got them, what stage of review they're at etc. It was nice to just suddenly get a message from Tim saying it "was fixed and should be appearing fine now". I enjoy using issuu.com and it is an important way for me and my students to connect; it's also a relief to know there are people there to help. Thank you!
