If educating is the purpose, then they can do it on other platforms, varsity, trading QA blog, emails. Either ways they send informative emails. Also just the other day, there was Admin message on some kids education series 'Rupee Tales'. Now what has this message do with trading?? Why put it on the terminal. Did this subject need any urgent attention for ALL traders. Either ways they sent email too on Rupee Tales, so that was fine. Like ways many times they send information which is not related to trading, but just promotional or marketing stuff. And this is unwarranted and unsolicited.
My point is they need to use this tool only for communicating IMPORTANT information, update which has effect on ALL TRADERS.
