Conversation-like fillable form

I know there are quite a few services such as the ones listed by rester that provide a similar service to what you're asking about. There is definitely quite a few to imitate Android, iPhone, and Tinder messages to create fake conversations. I've never really understood the point of them, but I'd also say that creating something like this wouldn't really be too difficult to do, just some basic HTML/CSS and then Javascript to add new messages in. With the right knowledge, shouldn't take more than an hour or two to complete a project like this except with fine-tuning looks and functionality.
