@moglika, Whats so complicated ??
Copy to your plugin folder and put in your e-mail address and your done!!
What do you want?
Edit: instructions are in the first post of this topic.

Complicated because the plugin doesn't work as is. Of course, I have read the instruction and followed it, but the plugin causes js not found errors. Reading forum's posts I haven't find working solution.
Besides, I didn't understand what a language file you mean and where it must be placed.
