I'm a research librarian at the U of Missouri in Columbia, MO and I wanted to change the information for my institution on https://www.zotero.org/support/locate/openurl_resolvers. This page indicated that it's a wiki, and allowed me to create an account separate from my regular zotero.org account, to edit the page, but when I tried to edit I was given a message that I don't have authorization to edit. I don't mind mediated editing on this page, but I do want to let you know that the open URL resolver for the University of Missouri is now http://library.missouri.edu/findit (no longer the 1cate URL). Thanks!
