I have used the "Report Typo" feature to submit an error and an omission in the Saints resource on St. Peter Canisius, SJ, whose Commemoration may be celebrated today in the Latin rite.
The error is to ascribe to him as a lesser-known name, in lieu of the ones that are true, that of the abbreviated Spanish name outside of religion of St. John of the Cross, OCD. These two great Counter-Reformation Doctors of the Church are certainly not the same person. 
(Aside: please consider adding some votes to the UserVoice suggestion for the Small Catechism for Catholics of St. Peter Canisius.)
