yeah no, I mean like literally let the user insert a message through a form, like <input type="text">, that thing you know? And then you could, like, save that. Just save that data. And read it. And respond. Something like that. THEY ARE ON A BROWSER. Am I crazy here? Please, anyone? What year is this? Where am I?
Just so you (person who is new to HN) understands why your comment is downvoted here - HN is more of a community for providing constructive feedback. Read the other comments on this post to get practical examples.
If I posted something I had poured my heart and soul into for months/years and had to deal with sarcastic vitriol from someone who completely misses the point of what I'm trying to accomplish, I wouldn't feel comfortable posting my work here. I'm personally very grateful there is a community like HN where negativity and closed-mindedness is grayed out.
