Conclusion
Through this tutorial we have covered the different options available to you with Collections. You should now have some background and insight to how each of the different settings and criteria work. With this the next step is to figure out what you want to display with your Collection and pick the criteria that will create that. Keep in mind that you can mix and match as many of the criteria as you want.
The more you work with collections, experiment, and explore, the more efficient and effective you will become at using them. The possibilities of Collections are great and are not just limited to a few examples. So go forth and explore.
