I don't mean to confuse you. If your forms do not have code, as I've mentioned, this is simply not an issue for you and you can keep publishing to a form library. If your forms did have code, and an email submit connection, you'd have to admin approve the form (as outlined in the link I provided above) to open them in the browser.
Admin approving a form template means it has been published in a specific fashion to a network location, uploaded to Central Admin and activated, then used as a content type in a form library.
