I would have to disagree with that one. I have written well over 1500 letters in Word and all are saved on my computer. They can all bed edited, but I am not concerned about HIPAA. If Jon were really trying to keep us from editing it and having a paper trail, one wouldn't be able to simply go in to the folders and delete them.
Plus, if that were the case, why wouldn't Jon have come on here years ago and just said that. I think it is just easy code-wise to save in HTML. Even while saving in Word or PDF would be better, it would be more than a one-step process.
