After purchasing a course via Groupon, I was told by their customer services, after having trouble logging in, that their course is only usable for Windows users, and that 'it's too much work to set it up for other operating systems'... meaning that millions of Mac and Linux users are effectively barred from using learndirect. This seems to be backward thinking on behalf of ld team, or they have some exclusivity arrangement with MS. Either way, it's a big thumbs down for them, and it seems they are not a forward looking, progressive company, or that they have the users interests at heart. How can any company deliberately close itself off from a huge section of the market and expect to survive in these troubled times is beyond me. Good luck without us, learndirect.
