I just installed this add-on (Version 1.3). The account creation screen does show the two email address fields. However, it appears as if the comparison check is not performed. The password check does work.

I've double-checked that the files have been placed in the correct directories, but I could have missed something.

Does anyone have a suggestion as to what file is misplaced or missing?
