It sucks that the "Powered by Olark" text is there even for paid accounts/that it is so big and it sucks even more that it can't be translated to other languages. English text on non-English websites looks incredible non-professional, so much so that even though I love all the other aspects of Olark I've considered switching.

From my Norwegian customer's perspective it looks like a free script. A Norwegian company, Idium, is actually successfully charging 3500 USD for a live chat solution inferior to Olark, but since it's in Norwegian they're able to do it.
