Well, the thing is, that the comment system does not support RTL languages. Normally I wouldn't even bother commenting about it, but since this addon is supposedly "multi language" I fealt I should write it to warn other people.
Luckily' it is really easy to convert the css file to RTL, took me 2 minuets or so. If anyone would like the RTL adjusted css file, contact me on: email@example.com and I will be happy to give it.
I believe the developers could easily overcome this (and hopefully will in later versions) by either connecting to the site aligning definitions or by adding an option to the backend for selecting RTL.
Anyhow, like I said- a great add on, better than other commenting addons IMHO. If I will have the time I may do a complete translation, but it probobly won't be anytime soon :)
Unfortunately, I do not know any of the RTL-languages, and therefore not entirely familiar with the situation. If you can advise me and explain that you need to add a component - I will make the necessary changes. Contact me at the forum and let's make the component even better!
