-It is free to keep '''''one''''' micro instance running at all times.  The AWS Free Tier includes 750 hours of Micro instance usage per month for a year; given that the longest month is 744 hours long, the Free Tier is enough to keep a single Micro instance running 24/7 for a year.  Keeping your instance running around the clock will make your life easier, because then you won't need to always change your hostname in your SSH clients.
+It is free to keep '''''one''''' micro instance running at all times.  The AWS Free Tier includes 750 hours of Micro instance usage per month for 6 months; given that the longest month is 744 hours long, the Free Tier is enough to keep a single Micro instance running 24/7 for six months.  Keeping your instance running around the clock will make your life easier, because then you won't need to always change your hostname in your SSH clients.
 For additional micro instances, or for larger instances, you will be charged hourly for their use.  One non-free micro instance costs about $14/month; a small instance costs about $43/month.

		+	When rebooting your instance using "Reboot", your instance address will not change. When rebooting your instance by clicking "Stop" and then "Start", your address WILL change.
		+
		+	For many assignments, you will need to submit a link to your code running on your instance. If you must reboot your instance, please use "Reboot" rather than the alternative to ensure your link does not become invalid.
