[Plugin: 2D Barcodes] Low Quality Overall

1. The plugin downloaded, installed and activated fine.
2. The site was in german and I spent about 10 minutes trying different things, translating, registering, searching etc, only to find that the code was in the welcome email.
3. On entering the code, it does generate a bar code, but:

a. the code is very badly formatted.
b. the surrounding text is in german
c. the code only contains a short link that redirects to my blog URL, nothing more. I was expecting the post text to be contained in the URL, which is not the case.

Uninstalled it from http://www.chefatlarge.in.
