Hey Guys,

Again thanks for this awesome project - having a lot of fun working with it! I have been having so much fun that I hit my stack limit on AWS for cloudformation...

After filling in the form and asking AWS to raise my limit I got this lovely bit of information back from them:

"Please keep in mind, that when you have above 20 stacks you should not use the DescribeStacks API without a stack name. Instead use ListStacks http://docs.amazonwebservices.com/AWSCloudFormation/latest/APIReference/API... because it is efficient. When called, DescribeStacks without a stack name will attempt to retrieve all stacks in that account and drastically impact performance; which is why we don't recommend its use."

I noticed that you guys are using DescribeStacks in your code and thought this information might be of some use to you! ;-) disregard if not :-P

Again Many Thanks! //P
