For corrigenda that are discretionary and a result of author-oversight (e.g. corrections in the affiliation etc) we charge a $190 processing fee to make changes in the original paper and publish an erratum. To request a correction, please submit a correction statement (text similar to http://www.jmir.org/2015/3/e76/) as new submission from your author homepage.
