Am I on the Right Track?

Hi!

    I'm just starting to pickup learning ruby on rails. I started
with it for awhile, but then quit because I was lost...and now I'm
picking it back up again.

    My question is, am I on the right track? I'm trying to develop an
application, and so far, it's working well. But, in the app/views
folder, there is a _form.rhtml file. If I wanted to change the form
around, can I edit that file, or is there another file that I should
be using?

Thanks!
Mike
