You don't necessarily need to sign up with a remote service to add value-added features to your site. You can add JavaScript scripts to you page or site that do not require any server support, since JavaScript is a client-side scripting program that creates scripts that run entirely on a user's system. There is a wide variety of JavaScript scripts that can be added to Web pages, including time and date stamps, date last updated, rollover buttons, clocks and timers, marquees, text scrollers and tickers, pop-up windows, e-mail address hiding, bookmarking, password protection, and more. Here are some sources of JavaScript scripts on the Web:
