Form or not to form?!

I am making a simple website with just one background page. On this page I want to have dynamic text box with a seperate input text line. The idea of the webpage is to have people input their ideas in the “input text line” than it shows up on the list. Not only do I wan that I want the ideas to accumulate and show everytime someone opens the page. I don’t think that falls under the form catagory or the database.

I just don’t know where to look.

Is there a simple solution?
