I might be 2 years too late, but is there a way to replace the whole php experience using js? I can't use php on the website tool I'm using but I also don't want to switch for community-reasons. It's a little niche community that I like to stay a part of, but I want comments on my page made by visitors. Designing isn't that hard, but I fail at the whole js/php magic though.
