I did not have absolutely any trouble installing the extension, except that I am new to Joomla, and had to guess, for instance, that there were 2 bots to install.

I also did not know I had to make some folders writeable. CHMOD... This too was not easy.

As I am a programmer, I can easily modify my contents to include the tags in the body. I first put the tag in the title and it didn't work. At first, I didn't guess I needed the er... tags around the tag itself !!

Anyway, the idea is very good, and it was all I wanted. Congratulations.

One note: the decimal point comes out in French (the comma), and the currency shows up as euro.
