Changing DOI Resolver
It would be very useful to have the ability to change the address used by Zotero for resolving DOIs (if only in about:config); for example, I would like to be able to change it to run through my university's EZProxy server.
Could you be more specific about what your trying to accomplish?
And by "when clicking on a link to a DOI within a citation" you are referring to the DOI field on the right hand side in Zotero, right?
