The Collector Achievement
Add 3 items to your watchlist
This achievement requires you to first set up an account with Crackle. Doing so is free and requires some personal information such as you birth date, email, password, login, ect. Doing this will also net you the, "Sign Me Up!" achievement in the process.
Once you are signed up, the achievement requires you to add three items to your "watchlist" which is sort of like an internal pin system for this app. To do this, simply select any TV show or Movie and select the option "add to watchlist," you really can't miss it. Add three different items like this and the achievement is yours.
