Maybe why don't you fix the lag? I was going to save my work and then suddenly it CRASHED CRASHED!!!!!!!! I just got a mac and it works perfectly fine and so is my internet. My teacher suggested that use this annotating website! one minute later ALL OF MY WORK IS GONE!!!!!!! AAHHAHAHAHAHAH KAMI IS MUCH BETTER THAN THIS. AT LEAST THEY HAVE AN AUTOMATIC SAVE. AND THIS app doesn't accept Outlook or something. I signed up with Outlook and look at where this app led me to.......................pain.
