Is there an HTML code out there like this?

You want this to be submitted to the server? so that if someone else go to the site they will se what you wrote?

You will have to use javascript for that.

it depends, if he want the stuff to stay that way from session to session it will need something like php and mysql.

yes exactly like chatroom, everyone can see what everyone wrote

johnpowell is there a code you have to put in to let it go into the box above without just dissapearing or doing something other than being entered?

You might be able to bend it to fit your needs. The link to download it is on the right of that page.

see, I’m wanting to me it from 100%scratch to tellmy friends “I made this”

I can’t really help with that. That is a project that you should know what is needed before stepping into.

You need a server with mysql and php support, and a lot of skills to do that.
