I believe all of you have received an email from Karl Cheung regarding the Markit testing environment. Please try to access the link provided in Karl's email and get back to him ASAP whether you can can successfully access it or not, since Karl will need to arrange the training session and he won't be able to do so if he can't get the confirmation from all of us.
If you already replied Karl, please disregard the message above and thank you for your quick response.
