I have a side project and I have made a simple homepage with a form where I need:
- user's email address
- some keywords which they are interested in.

I am noticing a problem here, people confuse this for to be a signup form and enter their email address and password (they obviously don't read the placeholder text).
This is a flaw in design since I am not able to convey the right information they need to pass.
I am thinking about:
- Adding autocomplete in the keywords field or
- Add an extra text on the right side of the text field like:
Keywords:
But not sure which one will work better and if there is anything else I can do about it.
So, any suggestions on how can this be improved?
Update:
- This is a one page app, there is no "user registration" mechanism on the site for now.


placeholderattribute to provide the placeholders for the input fields, make sure you also provide a JS solution as a fallback, as the placeholder attribute is not supported in IE, not even IE9, as far as I know, so perhaps some of your users don't even see the placeholders. – Victor Stanciu Nov 3 '12 at 7:27
