Well, if you're goal is to give surfers the free stuff right away, don't worry about using a warning page. You are not required by law to show a warning. However, a warning page at the root of your domain is considered due diligence - a minimal attempt at keeping youthful Christian folk out of your site. Surfers are quite accustomed to seeing them. Keep it clean with a simple and obvious navigation and it won't slow them down by more than a single click.

Excellent examples:
