Безопасен ли coursesmart.com?

Just one of many reasons why their service is terrible: their online reading web app will arbitrarily lock you out of some features depending on what browser you use (even if your browser supports the necessary features). Particularly the Offline Reading, which requires Firefox 3.6 but locks you out on Chrome or Safari, even though both of those support the HTML5 offline features that Coursesmart uses. Contacting their support about this resulted in a condescending canned email, followed by a representative telling me they had no plans to fix it.

This site is terrible. It only allows you to print so many pages, you can only copy and paste 1 paragraph at a time, you can only view so many pages at a time without the use of an internet connection, and when you ask for a refund they give you the run around. *****
