Don’t forget your ToS and Privacy Policy!

Every website that directly or indirectly provides any kind of service should have a Terms of Service and a Privacy Policy. These should be viewable from any page on the site. Even if nobody will ever read them, they should still be there.

The best and easiest place to put them is the footer. This is where they usually go, if you have a constant page template it’ll automatically be on every page, and here they won’t obstruct anything else. This may sound obvious, but just don’t forget about it ;)
